Shane Mosley retires from boxing
Former three-weight world champion Shane Mosley (47-9-1) has announced his retirement from boxing.
Mosley was stopped for the first time in his career against Australian Anthony Mundine last month, when he was unable to continue after six rounds due to a back injury.
During his professional career, the American won world titles at lightweight, welterweight and light middleweight.
In his most significant fights he scored two decision wins over Oscar De La Hoya, and engaged in ring wars with Miguel Cotto, Floyd Mayweather Jr and Manny Pacquiao.
"It's a young man's game," said the 42-year-old Mosley. "It's time to step aside and let some of these young guys do their thing. It's time to go."
Mosley said he will remain in the sport as a trainer. He is training his son, Shane Jr and other young fighters.
