Fightnews.com has confirmed that Manny Pacquiao will face Shane Mosley on May 7. The bout will be for Pacquiao’s WBO welterweight title (no catch weight) and will take place at the MGM Grand Garden Arena in Las Vegas. Mosley officially signed to do the fight today. Promoter Bob Arum said he turned to Mosley after Floyd Mayweather Jr. was unresponsive to doing the fight. Mosley, a partner with Oscar De La Hoya and Bernard Hopkins in Golden Boy Promotions, went rogue and negotiated the fight on his own against the wishes of Golden Boy, which preferred to have Juan Manuel Marquez face Pacman.
