Retrieved 27 June 2016. although he describes himself as "just a regular boxer".
In November 2019, Kovalev was ranked as the world's second-best light-heavyweight by The Ring magazine, third by BoxRec, and fourth by the Transnational Boxing Rankings Board. In 2014, The Ring named him its Fighter of the Year.Rosenthal, Michael (11 February 2015). "Sergey Kovalev named The Ring Fighter of the Year". The Ring. Retrieved 27 June 2016.
In 2004, Kovalev participated in the Russian Senior Championship for the first time, reached the finals, and won the gold medal in the team event. In 2005, he reached the peak of his amateur career and won two championships: the first as a champion of Russia and the second as a champion among servicemen. He won the silver medal in the championship for servicemen in 2006. In 2007, he finished third in both the Russian Championship and World Military Games in India.
In 2008, Kovalev participated in his final amateur competition and reached the finals, after which he decided to turn professional. Kovalev admitted that he felt forced to leave the national team because of the intense competition between him and others boxers such as Artur Beterbiev (to whom he lost 24–25). Kovalev finished his amateur career with a record of 195–18.
In July 2011, Kovalev won his first North American Boxing Association belt in a 10-round fight with Douglas Otieno from Kenya. His next bout against Grover Young was controversial: during the second round, Kovalev threw a left hook that the referee declared an illegal blow to the back of the head. Due to Young's inability to continue, the fight was declared a technical draw.
In his 2011 fight against Roman Simakov of Russia, Kovalev knocked down his opponent in the sixth round. The fight was stopped and Kovalev was awarded a TKO victory. Simakov was taken to the hospital, where he lapsed into a coma and died three days later.
In 2012, John David Jackson became Kovalev's trainer. Kovalev met Darnell Boone in the ring for the second time and knocked him out in the second round; the win led him to be signed on to Main Events boxing.
On 19 January 2013, Kovalev faced the former World Boxing Association (WBA) light-heavyweight champion Gabriel Campillo. Kovalev took advantage of Campillo's faltering defense and knocked him down with a left hook, one of three knockdowns in the round.
On 29 March 2014, Kovalev defended his title against undefeated Cedric Agnew (26–0, 13 KOs) at the Adrian Phillips Ballroom at Boardwalk Hall in Atlantic City. Although Agnew was not known to many boxing fans at the time, he won against Yusaf Mack, Daniel Judah, and Otis Griffin. Agnew's movement gave Kovalev difficulty at times, but after three falls, Agnew was finished in the seventh round. The fight drew an average of 1.048 million viewers on HBO. Although the figures were down from the Kovalev vs. Sillakh bout, the fight was televised at the same time as Wisconsin vs. Arizona, competing to reach the Final Four of the NCAA's college basketball tournament.
On 2 August 2014, Kovalev defended his WBO title against undefeated Australian contender Blake Caparello (19–0–1, 6 KOs) at the Revel Casino Hotel in Atlantic City, New Jersey, and it was televised on Boxing After Dark. Kovalev hoped for a unification fight against WBC champion Adonis Stevenson, but Stevenson stated he would only fight on Showtime; as Kovalev was contracted to HBO, he had to fight Caparello instead. Caparello scored a flash knockdown after catching Kovalev with a solid shot while Kovalev was off balance. Kovalev, however, was unhurt and even appeared enraged, and beat Caparello in a second-round technical knockout. The fight was watched by an average of 990,000 viewers and peaked at 1.052 million. Kovalev's victory allowed him to fight Bernard Hopkins in the fall of 2014. Main Events spokesperson Kathy Duva believed there was a loss of focus due to building pressure, which was why Kovalev was dropped by Caparello. Kovalev shrugged off any claims that he felt pressure, saying, "I didn't think about Bernard Hopkins tonight. I was focused on this fight. It is very important. A big step for me. If I do not win the fight, there is no fight with Bernard Hopkins." Lou DiBella, a promoter of Caparello, praised Kovalev, particularly the body shot that ended the fight. Negotiations for the Hopkins fight began prior to the Caparello fight.
Duva stated that Kovalev was looking for a homecoming bout next, likely on 28 November in Moscow, and stated she would call promoter Yvon Michel to set up a fight with two-time Olympian Artur Beterbiev (9–0, 9 KOs), who defeated Kovalev in the amateurs. The fight was unlikely to happen as Beterbiev was advised by Al Haymon, and performed on Premier Boxing Champions, who were banned by HBO.
Kovalev dominated the fight, both outpunching and outlanding Pascal by wide margins. Kovalev won when Roach refused to let Pascal continue after the seventh round. During the pause, the scorecards read 70–62 three times in favor of Kovalev. Round 5 was scored 10–8 on all three judges' cards without a knockdown. After the round, Roach threatened to pull Pascal. According to CompuBox stats, Kovalev landed 165 of 412 punches (40%) and Pascal landed 30 of 108 blows (28%).
After the fight, Kovalev said his future plans would likely include a fight with former super middleweight champion Andre Ward, but he first wanted a unification bout with reigning WBC and recognized Adonis Stevenson, a lineal champion. Kovalev called Stevenson "Adonis Chickenson" during the post-fight interview. Stevenson, who was in attendance, responded by confronting Kovalev in the ring surrounded by three bodyguards. The fight averaged 1.179 million viewers on HBO and peaked at 1.269 million viewers.
Kovalev had a warm-up fight on 11 July against Isaac Chilemba (24–3–2, 10 KOs) in Yekaterinburg, Russia, at the Palace of Sports; it was the first time in five years that Kovalev returned to Russia for a fight to defend his WBA (Super), IBF, and WBO light-heavyweight titles. Chilemba was known for having a similar style to Ward. Kovalev tipped the scales at 174.6lbs, while Chilemba weighed in at 174.8lbs. Kovalev earned a unanimous points decision after a hard-earned battle. The three judges at ringside scored the fight 117–110, 116–111, and 118–109 at the end of 12 rounds in favour of Kovalev, who retained his titles. In round 7, Chilemba staggered across the ropes and was downed by a straight left with a right to the jaw. The fight aired live on HBO and averaged 355,000 viewers.
Kovalev lost a closely contested controversial decision with all the judges scoring the fight 114–113 in favor of Ward. Larry Merchant stated after the fight, "It was a classic hometown decision, Kovalev won the fight!" Gareth Davies, boxing correspondent, gave the fight to Kovalev with 115–112, as did Max Kellerman. Duva, said, "We got a great fight, which is what boxing needed. But we also got a bad decision, which is not what boxing needed." Many boxing experts have applauded the decision: Paulie Malignaggi noted the high degree of difficulty both fighters faced that night and doubted the prospect of a one-sided affair in the case of a rematch, though he concluded that Kovalev faded late in the fight; promoter Eddie Hearn added that Kovalev lacked a sense of urgency after the halfway point; Gennady Golovkin's trainer, Abel Sanchez, noticed how Kovalev allowed Ward on the inside and as a result was worn down. For the fight, Kovalev received a minimum of $2 million and Ward a career-high $5 million. CompuBox stats showed that Kovalev landed 126 of 474 punches (27%), and Ward landed 116 out of 337 thrown (34%).

Ward commended Kovalev in the post-fight interview, "He's a good fighter, and I have nothing but respect for him. First time around, the man is world champion, and he's been on top a long time. I give him credit. He is a great fighter, and when you fight great fighters, you have to raise your game." Kovalev said the fight could have continued, "I don't know. I can't explain it. Not every round, but I thought I was doing very good. I was better, and he was better this fight. I didn't feel like I was getting knocked down with his punches --- I could have continued," Kovalev said. "I didn't feel the punch. This is fighting. We are boxers. Yes, he did punch me, but he didn't hurt me. The fight should have continued."
According to Yahoo Sports, the fight generated around 130,000 buys on HBO PPV. The replay was shown on regular HBO, which averaged 752,000 viewers and peaked at 947,000 during the final round.

Kovalev spoke to reporters in Russia on 27 June 2017, and confirmed that he would be making changes to his team, which included a new head trainer, meaning he would part ways with John David Jackson, and a new specialist. Due to having issues making the light-heavyweight limit, Kovalev considered moving up to cruiserweight. Reports also suggested that Ward's trainer, Virgil Hunter offered his services to Kovalev. On 26 October, Kovalev announced Abror Tursunpulatov as his new trainer. Tursunpulatov was most known for training and developing amateurs, such as the 2016 Rio Olympic Gold medalist Fazliddin Gaibnazarov.
Kovalev regained the WBO title after stopping Shabranskyy in round two. Kovalev knocked Shabranskyy down three times during the fight before it was stopped. Speaking to Max Kellerman of HBO, Kovalev said, "I did it. I worked really hard. Mentally, physically, I'm back. It's my goal to be the best in the division. Last fight I was stopped, it was a decision by the referee. Here tonight was great boxing for me and I love boxing and I am here to make great fights." He also went on to say that he would like unification fights going forward. CompuBox showed that Kovalev landed 50 of 113 punches (44%), this included 25 of 36 power shots in round two and Shabranskyy landed 16 of 71 thrown (23%). According to Nielsen Media Research, the fight averaged 869,000 viewers and peaked at 900,000 viewers.
The arena was a sell-out with a crowd of 5,642 in attendance. In a shocking upset, Álvarez won the fight via TKO in round 7 to claim the WBO title. Kovalev was knocked down three times in the seventh round before the fight was stopped. For the first six rounds, Kovalev fought well. He used his jab and landed right hands on the outside. Kovalev headed into round 7 ahead on the scorecards, 59–55, 59–55 and 58–56, but was caught and dropped hard by a one-two combination. He beat the count, but instead of trying to hold Álvarez in a clinch, he attempted to brawl, only to be dropped a further two times. Referee David Fields decided to stop the bout, with the time of stoppage at 2:45 of the round. Álvarez was detaining himself to the midway point of the fight before letting off some power shots. Álvarez explained that part of the game plan was to wait for Kovalev to tire.
After the fight, Duva confirmed there was a rematch clause in the contract, but was unsure if the rematch would take place straight away. Kovalev was hospitalized as a precaution. He thanked his fans for their support, and hinted at retirement. Through a translator, Álvarez said, "Words cannot describe how I feel. I want to thank God and all my fans in Canada and Colombia. This was all for them. It was a two-punch combination for that I have been throwing my whole career, and we worked on it in camp. I have always practiced that in camp, and we thought it would work in this camp." Kovalev was taken to hospital following the loss. He said in a video statement, "I feel OK. Thank you everyone. Thank you very much to all the fans around the world for your support. I love you, and I'm fine." Duva also noticed that Kovalev appeared to gas around the middle of the fight. According to CompuBox, through the seven rounds, Kovalev landed 91 of 339 punches thrown (27%) and Álvarez landed 73 of his 251 thrown (29%). Round 4 was the busiest of either boxer, where Kovalev landed 29 of 82 shots, 25 of which were power shots. The fight averaged 731,000 viewers on HBO, peaking at 813,000 viewers. An increase from Kovalev's last fight.
Before a crowd of before 4,877, Kovalev fought the perfect fight and put on a performance to regain the WBO title after defeating Álvarez via unanimous decision after twelve rounds. Álvarez won some of earlier rounds, however once Kovalev settled into a rhythm and using his jab, he was able to keep Álvarez at range, which he continued to do so for the remainder of the fight. Kovalev had better conditioning in the rematch with the main difference being instead of going toe-to-toe, he focused more on boxing. He fought smart and avoided clinches. Álvarez did his best to try and slug it out, using holds and head-locks. It was the corner advice from Buddy McGirt which really helped Kovalev stay focused between rounds. Kovalev slowed down the pace in the middle rounds. He appeared tired, but got his second win in the championship rounds to finish the fight strong. The judges scored it 120–108, 116–112 and 116–112 for Kovalev. Following the fight, Kovalev said, “My goal was to box. He was looking for the big punch, but I kept boxing. The only time I got hurt was when I got a thumb in my eye.” Álvarez had no excuses, but felt if it came down to a decision, he would have lost. Álvarez did not feel like he lost the fight, but accepted the decision. According to CompuBox, Kovalev landed 213 of 816 punches thrown (26.1%) and Álvarez landed 111 of his 369 punches thrown (30%). Kovalev out-landed Álvarez in 11 out of the 12 rounds.
Álvarez's promoter Yvon Michel faulted the teams strategy going into the rematch feeling confident in stopping Kovalev, much like the first fight. Álvarez later admitted he was too focused on knocking out Kovalev. He said, "It was not my night, I admit that I tried to knock him out, that was my plan, but things did not work out. I wanted to end it before the twelfth round, but it didn't happen." He was scheduled to take a few days away from training but called for a trilogy fight. According to Kathy Duva, the rematch did not have the same feel as the first fight, thus not warranting a third fight.
On 12 July, after months of negotiations, the fight between Kovalev and Yarde was formally announced by the Russian Boxing Federation, to take place at Traktor Ice Arena in Kovalev's hometown of Chelyabinsk, Russia. Yarde told the press, “This is my time now and I am going to show the world what I am all about. I am more than happy to achieve my goal in Russia and I think it is only right that a great world champion such as Kovalev is given the opportunity to defend in his home country. He has earned that right." Frank Warren was confident in Yarde being victorious and stated the it was a key reason as to allowing the fight to take place in Russia.
On 25 July, it became known that Kovalev was negotiating a deal to fight Saul Álvarez in October 2019, in a fight that would see Álvarez make his light heavyweight debut. There was reports implying the fight with Yarde would be scrapped if Golden Boy Promotions and Main Events successfully negotiated a deal. Álvarez was ordered by the IBF to defend the title against Sergiy Derevyanchenko. John Skipper, who was DAZN's executive chairman, where Álvarez was tied into a contract, stated the steaming service would only approve Kovalev or a trilogy fight with Gennady Golovkin as Álvarez's next fight. According to Egis Klimas, an agreement was in place for Kovalev to fight Álvarez, if he was to defeat Yarde. On 8 August, Álvarez decided to wait until after Kovalev's fight with Yarde to decide his next opponent. Yarde revealed he was approached multiple times for step aside offers. He was first offered less than his purse for the Kovalev fight, then offered the same amount. Yarde joked that these offers needed to be more than double his purse for him to consider stepping aside. During fight week, Kovalev spoke to reporters to explain the reason why he turned down a last minute eight-figure offer from Álvarez was due to the Yarde fight only being three weeks away. Tickets were already on sale and being sold. Also the matter that Kovalev was defending his world title in front his own fans in his hometown, having fought the majority of his career in the United States. Speaking to Steve Bunce, Kovalev said he wanted five more fights and a chance to become undisputed champion. Yarde made it his mission to win the fight by knockout and ruin Kovalev's plans to fight Álvarez.
After 11 rounds, Kovalev knocked out Yarde, ending the fight via TKO and retaining his WBO and ESP light-heavyweight titles. Yarde seemed comfortable in the early rounds, staying out of range and keeping Kovalev at bay with speed and movement. After six rounds of an even, back and forth contest, Yarde began landing hooks to Kovalev's body in the seventh and eighth rounds that appeared to hurt him. In the last minute of the eighth, Yarde landed a straight-right to the head of Kovalev which had him in trouble. Yarde followed up with a salvo of power punches but was unable to capitalise, allowing the visibly hurt Kovalev to stay on his feet for the remainder of the round. After this success, Yarde appeared tired and lose momentum, allowing Kovalev to take control of the fight with combination punches and stiff jabs that began to frequently land on Yarde. The tenth round saw much of the same. In the final 20 seconds of the ninth round. Yarde was seemingly saved by the bell, which appeared to ring 8 seconds before the end of the round. In round eleven, sensing Yarde's fatigue, Kovalev upped the pressure and increased his punch output, eventually dropping Yarde with a spearing left-jab to win the fight by knockout. At the time of the stoppage, all three judges had Kovalev ahead with the scorecards reading 98–92, 97–94 and 96–93.
According to CompuBox, Kovalev landed 223 of his 686 punches (32.5%) while Yarde landed 132 of his 575 punches (23%), the most punches any fighter has landed on Kovalev. After the fight, Kovalev praised Yarde for his toughness, saying that Yarde "will 100% percent become a world champion one day". Buddy McGirt was close to stopping the fight after eight rounds. Kovalev pleaded with him to allow the fight to continue as he believed Yarde was beginning to tire. McGirt believed Yarde only got more confidence in the fight as Kovalev became lazy. After the fight, McGirt approached Yarde's locker room and told him, “you surprised me.” Kovalev was now ready for his next challenge.
After the fight, Kovalev suggested that he had always been unlikely to win the fight, due to the gruelling schedule of back-to-back training camps which resulted from the short period of time between the Yarde and Álvarez fights, but had agreed to fight the latter regardless due to the high financial incentive, which was reported to be $12 million (£9 million). Álvarez responded by calling Kovalev a "bad loser".
Not long after the fight was made official, the card was postponed, along with many other boxing events due to the coronavirus pandemic. At this time, Golden Boy were unable to offer a new date due to the uncertainty of the pandemic and how it would affect sports in the coming months. The fight with Kovalev was a proposed two-fight plan for Barrera. He anticipated a win over Kovalev would earn him a world title fight, for him to then retire from boxing. Barrera was still in the gym training and joked that he hoped Kovalev had not Alcohol addict. In November, it was reported the fight could be rescheduled to 30 January 2021.
On 16 December, it was announced that Kovalev would return to the ring on 30 January, however instead of fighting Barrera, he would return to Moscow at the Luzhniki Arena against 24 year old Uzbek prospect Bektemir Melikuziev (6–0, 5 KOs) on DAZN. Melikuziev previously fought at super middleweight. The fight was set for a contractual weight of 178 pounds. On the fight taking pace in his home country, Kovalev said, “I am glad that after a long break I am starting my journey back to the title of world champion. The fact that this fight is scheduled to be in Russia gives me even more motivation and strength.” Melikuziez showed respect towards Kovalev, calling him 'one of the biggest boxing stars of the last decade'. With only two weeks until fight night, the card was moved to Fantasy Springs Casino in Indio, California, without any fans in attendance. According to one source, the move was done due to health and safety concerns, which meant everyone involved would not have to travel. It was also reported the card would take place in the afternoon on the West Coast, so it would be broadcast during prime time in Russia.
On 14 January, Kovalev tested positive for synthetic testosterone, putting the fight in jeopardy. The test showed external testosterone and metabolites. Melikuziev put out a tweet stating, "It makes no difference to me. Just put him in the ring, let us fight regardless." All camps were notified by VADA on 13 January. The fight was officially cancelled a day later. Kathy Duva released a statement saying Kovalev has always proven to be a clean fighter and will continue to prove this. The test which came back positive was administered on 30 December 2024. A week later, it was reported that a second test which was conducted on 7 January 2021, also came back as a positive test for synthetic testosterone.
On 1 June, it was reported that Triller had not paid Kovalev and both Pulev brothers for the event. Jerry Forrest, who lost a decision to Kubrat Pulev, had received a partial payment. Triller Fight Club president David Tetreault told all parties involved the purse payments would be postponed up to 75 days, until they settled with a deadline of 31 May 2022. According to the contracts, Kovalev was guaranteed a minimum $500,000 purse.
On 31 January 2023, the WBC ordered a semi-final eliminator between Kovalev and South African former two-time world title challenger Thabiso Mchunu (23–6, 13 KOs), with a deadline set for 24 February. Mchunu was on a 4-fight win streak since his disputed split decision loss to world champion Ilunga Makabu.
Safar out-worked and broke down Kovalev throughout the fight, eventually dropping him in the tenth and final round, on his way to a unanimous decision win. The three judges scored the bout 97–92, 99–90 and 95–94 in favour of Safar. Kovalev started the fight with his trademark jab, whilst Safar aimed for the body. Kovalev stumbled after being hit on the chin in round 3. During the middle to late rounds, Safar was out-landing Kovalev. In the final round, Safar landed a left-right combination to Kovalev's chin, dropping him for an 8-count.
Kovalev finished his 16-year career at the Yunost Arena, with a seventh round TKO win over Mann. In the second round, Mann was dropped from a short left. He beat the count, but was visibly hurt and got through a barrage of heavy punches. He was dropped again at the end of the round, but this was ruled a slip. Mann did well in the third and fourth rounds, tagging Kovalev with short punches, but at the same time on the receiving end of stiff jabs from Kovalev, which opened up a cut over his right eye. The ending came after Kovalev landed a left, right left combination, dropping Mann. He beat the count, but seeing he was unsteady legs, his corner stopped the fight. The official time of stoppage was 0:49 of round seven. The knockout was the 30th in his career and his record improved to 36 wins, 5 losses and 1 draw.

In January 2020, the accuser filed a new lawsuit against Kovalev in federal court in Los Angeles, alleging that the parties reached a $650,000 settlement in October 2019, but that Kovalev then breached the agreement by not making the agreed-upon payments. Because the original suit was not to be dismissed until Kovalev paid the entire $650,000, that suit also remained active. The victim voluntarily dismissed the breach of contract lawsuit in September 2020, but the original assault lawsuit remained pending and was set for trial beginning in January 2021.
On October 2, 2020, three days before his felony assault trial was scheduled to begin, Kovalev pleaded guilty to a misdemeanor charge of fighting/noise/offensive words and was sentenced to three years of probation and two days of time served. He was also required to complete an anger management course and pay court costs. A few weeks later, Kovalev's accuser filed to dismiss her assault lawsuit.http://openaccess.sb-court.org/OpenAccess/CIVIL/CivilDetails.asp?courtcode=X&casenumber=DS1902333&casetype=CIV&dsn=
