Floyd Mayweather Jr. finalized a deal yesterday to fight Sugar Shane Mosley on May 1 in a welterweight bout at the MGM Grand Garden in Las Vegas.

Mayweather (40-0, 25 KOs) agreed to the 12-round bout last week, but hadn’t formally signed the contract for the former pound-for-pound champion’s second fight back from a brief retirement.

“This one is definitely for the fans, as I wasn’t going to waste anyone’s time with a meaningless tuneup bout and asked to fight Shane immediately,” 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.”
