Former three division world champion "Sugar" Shane Mosley (49-10-1, 41 KOs), 45 years old, has decided to join the recent pack, by announcing his retirement from boxing.
In the last few weeks, Wladimir Klitschko, Juan Manuel Marquez, Timothy Bradley and Robert Guerrero made their own retirement announcements from the sport.
"I decided that I'm older now. I'm not the same as I used to be, so I need to let it go as far as me trying to compete as a fighter anymore," Mosley told ESPN. "I'm definitely always going to be around boxing. I'll still go to the gym and show people stuff, help them out. I still love boxing. It's still my life but just not as a fighter anymore."
Mosley has been out of the ring since losing to then WBA interim-welterweight champion David Avanesyan on May 28, 2016.
There was a scheduled fight in Russia against undefeated prospect Magomed Kurbanov, but it was canceled after Mosley underwent surgery for an elbow injury.
"What happened was my arm is breaking down, my knees, shoulders," Mosley said. "My back is starting to break down. My body is telling me I'm older and I can't do it at 100 percent. I can't see myself fighting again. I'd have to say I'm retired."
Mosley capture world titles at lightweight, welterweight and junior middleweight. He fought a who's who of top names - including Oscar De La Hoya (twice), Fernando Vargas (twice), Vernon Forrest (twice), Antonio Margarito, Floyd Mayweather Jr., Ricardo Mayorga (twice), Manny Pacquiao, Saul "Canelo" Alvarez, Miguel Cotto, Winky Wright (twice) and many more.
He is considered to be one of the best lightweights in the history of the sport, but made his mark when he jumped straight to welterweight and secured an upset decision win over De La Hoya in 2000.
Mosley also made headlines outside of the ring, when disclosed to a grand jury during the BALCO scandal that he had used performance-enhancing drugs while preparing for the rematch with De La Hoya in 2003. Mosley has long claimed that he did not knowingly use any banned substances and claims that he was under the impression that all of the products being used were legal.
Mosley and De La Hoya would become business partners in Golden Boy Promotions - until Mosley departed from the company around 2011 to take a fight with Pacquiao.
