MANILA, Philippines (UPDATED) - Filipino boxing legend Manny "Pacman" Pacquiao is set to undergo surgery to repair his injured right shoulder that severely hampered his performance against Floyd Mayweather Jr. last week.
Dyan Castillejo of ABS-CBN News reported Tuesday that Pacquiao, after consulting with a doctor in Los Angeles and having an MRI scan done, has decided to go under the knife to repair the shoulder that he injured during training camp.
The surgery will take place sometime this week, Castillejo reported.
ESPN.com earlier reported that Dr. Neal ElAttrache, who has worked with other elite fighters including Kobe Bryant of the Los Angeles Lakers, said that Pacquiao has a "significant" tear in his right rotator cuff.
The boxer is expected to be out for nine to 12 months.
Pacquiao suffered the shoulder injury in training camp with three weeks to go before the fight, but still opted to push through and face Mayweather in the "Fight of the Century."
Pacquiao said he was able to rest his shoulder in the final weeks of camp, even sending away his sparring partners, and was under the impression that he will be allowed to take an anti-inflammatory shot on fight night in order to numb the pain.
The Nevada State Athletic Commission (NSAC) barred him from taking the injection, however, and the injury was aggravated in the third round, Pacquiao said after the bout.
The "Pacman" threw fewer punches than Mayweather, and he later told reporters that he was essentially one-handed as he could not use his right hand to unload power punches. -- Report from Dyan Castillejo, ABS-CBN News.
