Floyd Mayweather Jr. vows to walk away after Saturday

Nineteen years and 48 fights haven’t taken a big toll on Floyd Mayweather Jr., but he’s not taking any chances. He is determined to leave boxing with his brain fully intact. Rich beyond belief, Mayweather doesn’t need to fight anymore. And he says he’s comfortable walking away from the sport. “Not gonna miss it at all,” Mayweather said. Those not on the inside in the Mayweather camp scoff at the thought he will retire after facing Andre Berto today. They wonder how he can resist trying to break the late Rocky Marciano’s perfect mark of 49-0 and – perhaps more important – resist the huge money another fight would bring. – AP
