Manny Pacquiao

When Manny Pacquiao said he fought with a right shoulder injury, it wasn’t a ploy to land a rematch with Floyd Mayweather.

The Filipino boxing star is now set to undergo right shoulder surgery later this week to repair a “significant tear” in his rotator cuff, orthopedic surgeon Dr. Neal ElAttrache told on Monday night (May 4). “We have an MRI scan that confirms he has a rotator cuff tear. He has a significant tear,” the doctor says.

Pac-Man is expected to be out of commission for nine months to a year, if the surgery and rehabilitation go well.

Floyd Mayweather said, after their fight on Saturday (May 2), that he planned to fight in September for the final time before retiring. If he sticks to his schedule, it could rule out a possible rematch with Pacquiao.

Manny lost a unanimous decision to Mayweather (48-0, 26 KOs) in their long-awaited megafight.

“Manny did the best he could under the circumstances,” Pacquiao adviser Michael Koncz tells ESPN. “We have to give Floyd credit, too. Floyd was the better man [Saturday] night. Floyd did a tremendous job, and he won the fight.”

The fight was slow and mostly uneventful. The aggressiveness we are used to seeing from Pac-Man just wasn’t there, leaving fans disappointed. After the fight, Top Rank promoter Bob Arum said Pacquiao suffered a shoulder injury in training camp three weeks prior, which hindered his ability to attack in his usual style in the fight.

At the postfight news conference, Mayweather wasn’t interested in Pacquiao’s “excuses,” saying he too has fought injured.

“If [Pacquiao] would have come out victorious, the only thing I could have got up here and said was, ‘I have to show respect and say he was the better man,'” Mayweather said. “Both my arms were injured. Both my hands were injured, but as I’ve said before, I always find a way to win.”
