Manny Pacquiao undergoes successful shoulder surgery

Manny Pacquiao has already undergone surgery to repair a torn rotator cuff in his right shoulder, and the procedure is considered successful, with the 36-year-old Filipino superstar expected to make a full recovery and fight again.

Pacquiao (57-6-2, 38 KO) lost a 12-round unanimous decision to Floyd Mayweather last Saturday night, and immediately after the fight publicly disclosed the shoulder injury, which reportedly was suffered roughly two weeks before the bout. There was also an issue with Pacquiao not being allowed a numbing injection prior to the bout, as his team had failed to check the box on his medical questionnaire that indicated an injury, though they did list the medications he had been taking to treat it.

The injury is expected to keep Pacquiao out of active competition for 9-to-12 months, with 4-to-6 months the earliest he may be able to begin light training again. It's highly unlikely that he'll fight again in 2015, but there are already hints of a May 2016 rematch with Mayweather.

Pacquiao is also potentially facing a perjury charge in Nevada, which comes after he claimed that the commission sabotaged him by not allowing the lidocaine cocktail injection.
