By Dan Ambrose: 40-year-old former three division world champion Shane Mosley (46-8-1, 39 KO’s) has reportedly retired as of today, according to RingTV. Mosley, who turns 41 in September, was recently dominated by WBC junior middleweight champion Saul Alvarez in a one-sided 12 round decision loss last month on May 5th.

Mosley told RingTV “When the kids start beating you up, maybe it’s time to start promoting.”

Mosley plans on working as a promoter from now on. He’s made enough money to never have to work again just from his loss to Manny Pacquiao last year, but he’s not one to sit and do nothing with his life.

Mosley’s friend Hassan Abdulrahim told RingTV “Shane Mosley has officially retired, and he’s going to go into the promotional side of the sport.”

The high point of Mosley’s career was his first victory over Oscar De La Hoya in in June 2000. Mosley would later beat De La Hoya again in 2003 in a controversial decision. However, Shane had problems against fighters Ronald “Winky” Wright and Vernon Forrest, losing to both fighters twice each.

Mosley’s career tanked after he decided to sit out of the sport for a year after beating WBA Super World welterweight champion Antonio Margarito in January 2009. Instead of staying active, Mosley sat out a year until coming back in May of 2010, and losing to Floyd Mayweather Jr. by a lopsided decision. Mosley looked like he’d aged in that time off from the sport and he never seemed to come back from that.

He fought equally poorly in a controversial 12 round draw against Sergio Mora in September 2010. Following that, Mosley came back seven months later and was easily beaten by Manny Pacquiao in May of last year. Mosley then took another year off and came back against Saul Alvarez and was totally dominated in a 12 round decision loss.
