Filipino boxing star Manny Pacquiao has had successful surgery to repair a torn right rotator cuff in Los Angeles.

Doctor Neal ElAttrache, of the Kerland Jobe Orthopedic Clinic, said he couldn’t be more pleased with the results of the procedure on the 36-year-old.

• Mayweather might be the best we’ve ever seen

ElAttrache has also operated on the shoulders of NFL star Tom Brady and basketballer Kobe Bryant.

The operation follows Pacquiao’s 12-round unanimous decision loss to Floyd Mayweather on Saturday in Las Vegas in the most lucrative fight in boxing history.

The super-fight cemented unbeaten American Mayweather as the top pound-for-pound fighter of his era.

But Pacquiao’s camp revealed after the fight the Filipino had suffered a rotator cuff tear in training camp which he aggravated early in the bout.

The injury, Pacquiao’s decision to fight through it and questions over whether he adequately informed Nevada boxing authorities about it have combined to spawn a spate of lawsuits from boxing fans who say his “Fight of the Century” against Mayweather should never have gone ahead.

At least five lawsuits in various states have been filed against Pacquiao, promoter Top Rank and other entities, claiming they defrauded the public in failing to disclose his injury.
