Manny Pacquiao has shoulder surgery (The Associated Press)

Manny Pacquiao underwent surgery on his injured right shoulder Wednesday following his loss to Floyd Mayweather Jr. in boxing’s richest fight ever. Pacquiao spokesman Fred Sternburg quoted the fighter’s surgeon, Dr. Neal ElAttrache of the Kerlan Jobe Orthopaedic clinic in Los Angeles, as saying he could not be ”more pleased with the results” and fully expects Pacquiao to be back in the ring. The surgery came four days after Pacquiao fought Mayweather at the MGM Grand hotel in Las Vegas, dropping a unanimous 12-round decision. Pacquiao asked for a pain killing shot before the fight for his shoulder, but was denied by Nevada boxing officials because they weren’t aware previously of the injury.
