Promoter and former world champion boxer

Promoter and former world champion boxer Oscar De La Hoya (C) announces the Floyd Mayweather (2nd L) and Shane Mosley (R) May 1 fight during their joint press conference in Los Angeles on March 4, 2010. Floyd Mayweather will take on Shane Mosley in a marquee welterweight matchup on May 1, with both fighers agreeing to "Olympic-style" drug testing - an issue that scuppered Mayweather's fight with Manny Pacquiao. "This one is definitely for the fans as I wasn't going to waste anyone's time with a meaningless tune-up bout and asked to fight Shane immediately," the unbeaten Mayweather said. "I have said ever since I came back to the sport that I only wanted to fight the best. I think Shane is one of the best, but come May 1, he still won't be great enough to beat me."
