Roger L. Mayweather (April 24, 1961 – March 17, 2020) was an American professional boxer who competed from 1981 to 1999 and later on a boxing trainer. He was a two-division world champion, having held the World Boxing Association (WBA) and Ring magazine super featherweight titles from 1983 to 1984, and the World Boxing Council (WBC) light welterweight title from 1987 to 1989. Additionally he held the IBO light welterweight title in 1994, and the IBO welterweight title from 1994 to 1995.
Mayweather served as the trainer for his nephew, Floyd Mayweather Jr., from 2000 to 2012. He emphasized the Michigan Defense and use of a defensive technique known as the shoulder roll. Under Roger's guidance, Floyd Jr. became one of the biggest names in the sport of boxing and one of the pound for pound greats.
After improving his record to 14–0, Mayweather earned a title shot on January 19, 1983, against lineal and WBA super featherweight champion, Samuel Serrano. Serrano entered the bout with a record of 47–5–1 and had lost only once since first winning the title in 1976. Nonetheless, Mayweather led on all three judges' scorecards before he beat Serrano by TKO in round eight and effectively ended Serrano's career.
Mayweather made two successful title defenses against Jorge Alvarado and Benedicto Villablanca before suffering his first loss via first-round knockout against Rocky Lockridge on February 22, 1984.
Mayweather won the IBF-USBA super featherweight title when he gave Kenny Baysmore his first loss, by TKO in round three. Thus, Mayweather earned the opportunity to fight against WBC super featherweight champion, Julio César Chávez, on July 7, 1985. Although Mayweather won the first round on the judges' scorecards, he was knocked down twice in round two and lost by TKO.
On November 28, 1986, Mayweather beat Sammy Fuentes for the WBC Continental Americas lightweight title. In his next bout, on March 28, 1987, Mayweather fought against Pernell Whitaker for the WBC-NABF lightweight title. Mayweather was knocked down in round one, but he knocked down Whitaker in round nine. Whitaker won by unanimous decision (UD).
Mayweather made four successful title defenses before he encountered Mexican champion Julio César Chávez again on May 13, 1989. Prior to this fight, Mayweather was being called by several boxing writers as "The Mexican assassin" due to his numerous wins over Mexican fighters during the last few years. Chávez was still undefeated at the time, and with a 63–0 record, he was becoming a legend. Mayweather retired after round ten due to the body damage inflicted by Chávez.
Mayweather won the WBA Americas light welterweight title on April 5, 1990, from Ildemar Paisan. He fought Rafael Pineda for the vacant IBF light welterweight title on December 7, 1991, but he lost by KO in round nine.
On March 14, 1993, Mayweather beat former WBA lightweight champion, Livingstone Bramble by corner stoppage in round five. Bramble had defeated Ray Mancini twice for the title in the mid-1980s.
Mayweather defeated Eduardo Montes for the IBO light welterweight title by third-round KO on May 28, 1994. Less than three weeks later, he defeated Marco Antonio Ramirez by TKO in round three.
On June 25, 1995, Mayweather fought the 14–0 Kostya Tszyu for the IBF light welterweight title. Tszyu won by unanimous decision.
Mayweather won his last title—the IBA welterweight title—on March 12, 1997, when he beat Carlos Miranda via twelfth-round TKO. Mayweather's final bout was a majority decision victory over Javier Francisco Mendez on May 8, 1999. He ended his career with a total of nine major and minor titles in four weight classes.
"It's funny because I wanted a boxing nickname that wouldn’t be common to most people. One day when I was flipping through channels and I came upon this channel showing different reptiles, and they were showing the black mamba, one of the most deadly snakes in the world. I loved the way the mamba attacked so quietly, but when he hit you he just hit you one time and the venom was in you. That reminded me of myself right there."
Roger Mayweather garnered national attention during and after Floyd Mayweather Jr. vs. Zab Judah on April 8, 2006. Near the conclusion of the tenth round, Judah hit Mayweather with a left hand that was clearly below the belt and followed up with a right-handed rabbit punch. After referee Richard Steele called time with five seconds remaining in the round, Roger Mayweather entered the ring, but was restrained by Steele. Judah's father and trainer, Yoel Judah, entered the ring and swung at Roger. Zab then went after Roger—taking a swing and grappling with him until security broke it up and cleared the ring. Roger was ejected, but the boxers finished the remaining two rounds, and Mayweather won by unanimous decision. Five days after the fight, the Nevada State Athletic Commission decided not to overturn the result of the bout, but Roger Mayweather was fined US $200,000 and suspended for one year.Vester, Mark.

He did not specify the cause, but said his uncle's “health was failing him for several years.” Roger Mayweather had a number of long-term health problems, including diabetes.
"My uncle Roger Mayweather has lost a lot of memory from the sport of boxing, he's only in his 50s, but it seems like he's an old man in his 80s." Floyd said. Il ricordo El boxeo de luto: excampeón Roger Mayweather falleció a los 58 años
