With Andre Berto having pulled out of his Jan. 30 fight with "Sugar" Shane Mosley because of the massive earthquake in Haiti, Golden Boy Promotions CEO Richard Schaefer said Monday afternoon he is already trying to put together a fight between Mosley and Floyd Mayweather Jr.

Mayweather was scheduled to fight Manny Pacquiao on March 13 at MGM Grand in Las Vegas, but that fight fell apart over Mayweather's request for Olympic-style drug-testing for both fighters.

"I know this is the fight Shane wanted and I know it is a fight Floyd wanted as well," said Schaefer to BoxingScene.com. Golden Boy promotes Mosley and has a working arrangement with Mayweather. "So now I'm going to work and see if we can put that fight together."

Schaefer and Golden Boy still have the MGM Grand reserved for March 13 for Mayweather. But Schaefer wouldn't say whether Mosley-Mayweather would fill that date, or a different one, such as May 1.

"I think the first thing is going to be to see if a deal structure can be done, and then worry about the date," Schaefer said. "Floyd Mayweather against Shane Mosley is one of the biggest fights in the sport. They are two superstars, it would be a pick-em fight.

"The date will fall into place, but the first thing is to find a deal structure that is acceptable to everyone. That is what I'm working on."
