Mayweather-Mosley bout official

LAS VEGAS (AP)

Floyd Mayweather Jr. finalized a deal Wednesday 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."

Although the fight is an intriguing matchup between two veteran welterweights who have been circling each other for a decade, the dangerous Mosley (46-5, 39 KOs) still isn't Mayweather's first choice.

Mayweather agreed to the bout only after several weeks of negotiations with Manny Pacquiao failed to produce an agreement on what's likely to be the richest fight in boxing history, if it ever occurs. Pacquiao balked at Mayweather's stringent drug-testing demands, and instead will fight welterweight Joshua Clottey on March 13 at Cowboys Stadium.

Mayweather and Mosley agreed to participate in Olympic-style drug testing for their fight, saying they hope to set a new standard for safety in boxing. Mosley has acknowledged using steroids before a victory over Oscar De La Hoya in 2003, but claims he did so inadvertently under the direction of the BALCO lab.

Mosley was scheduled to fight Andre Berto on Jan. 30 at Mandalay Bay before Berto dropped out while dealing with the earthquake in Haiti, his family's home country.

"I have always wanted to fight Floyd, and now it is finally coming true," Mosley said. "I am already in great shape and ready to show everyone on May 1 that I am stronger, faster and better than he is. I will have no problem beating him."

Mosley, the 38-year-old WBA welterweight super champion, has been vocal about his desire to meet Mayweather ever since Mayweather celebrated his ring return last September with a one-sided victory over Juan Manuel Marquez. Mosley, a partner in Golden Boy Promotions, jumped into the ring after Mayweather's win and called out the unbeaten fighter.

But Mayweather appeared to be focused on the biggest payday of all against Pacquiao until his hard line on drug testing scuttled the fight and prompted Pacquiao to sue much of Mayweather's camp, claiming several members had defamed him by intimating he uses performance-enhancing drugs.

"Shane Mosley is one of the greatest fighters of this era, and I commend him for not only agreeing to the fight against Mayweather, but also agreeing to participate in a testing process that can only help the integrity of the sport," Golden Boy CEO Richard Schaefer said.

Mayweather didn't sign the deal until five days after Mosley formalized his commitment last Friday, prompting worries for Mosley's management and Schaefer, who represented Mayweather throughout the torturous negotiations with Pacquiao's promoters at Top Rank. Schaefer had hoped to get both fighters to Miami this week to promote the bout to the assembled fans and media at the Super Bowl.

Just a few days ago, Schaefer publicly acknowledged he was worried Mayweather might be having second thoughts about a tough fight against Mosley, who has only improved with age.

Mosley's only loss since late 2004 is a narrow, competitive decision to Miguel Cotto in November 2007. He has fought just twice since then, stopping Ricardo Mayorga and former champion Antonio Margarito, although Mosley was scheduled for fights against Zab Judah and Berto that were canceled by his opponents.

Mayweather should have the services of Roger Mayweather, his uncle and longtime trainer. Roger Mayweather has a June 1 trial date in Las Vegas on several serious charges related to accusations of beating and choking a female boxer last summer at an apartment he owned.
