Mayweather retires again

Unbeaten welterweight Floyd Mayweather Jr. has announced his retirement again, with boxing’s unofficial pound-for-pound king saying he no longer has the passion necessary to fight. The 31-year-old former U.S. Olympian (39-0, 25 KOs) hasn’t fought since beating Ricky Hatton in December, but was widely expected to fight Oscar De La Hoya in September in a rematch of the richest fight in boxing history.
