The rematch of American professional boxer Floyd Mayweather is uncertain as Manny Pacquiao will be undergoing shoulder surgery, keeping him out of the ring for 9-12 months.
Pacquiao complained of an injury after he was defeated on points by the American boxer in Las Vegas on Saturday.
The orthopedic surgeon Neal ElAttrache said that they had an MRI scan which confirms Pacquiao has a rotator cut off tear, the Mirror reported.
The much anticipated 'Fight of the Century' didn't quite live upto the hype, as Mayweather was very defensive in approach before he was declared the winner on points by unanimous decision.
The unbeaten American boxer said that he would fight once more before calling it quits.
Now, with Pacquiao not available for the fight, chances of British boxer Amir Khan squaring off with Mayweather have increased.
