- Floyd Mayweather said he is more likely to end up in movies than keep boxing, as he rounded on his critics ahead of what he insists will be his last fight. The unbeaten Mayweather takes on massive underdog Andre Berto on September 12 in Las Vegas in a welterweight world title fight aiming to equal the 49-0 record of heavyweight legend Rocky Marciano before hanging up his gloves. In a conference call with reporters, Mayweather said there had been "signficant" entertainment offers for the champion for when he calls it quits -- including three "major" movie possibilities. "I've been approached on numerous occasions (to act) but I'd rather be behind the scenes. I've had my time to shine," said Mayweather.
