Mayweather changes mind on rematch

Floyd Mayweather has branded Manny Pacquiao a "sore loser" and a coward and says he won't delay his planned retirement to grant the Philippine icon a rematch next year, in an apparent U-turn.

And he dismissed Pacquiao's claim that he had been carrying an injury in Saturday's one-sided win for Mayweather, the American calling it "excuses”

Mayweather took his unbeaten record to 48- nil in Las Vegas with a 12-round unanimous decision over Pacquiao in a welterweight world title bout that will go down as the most lucrative in boxing history.
