Pacquiao fought with shoulder injury; wasn't allowed to take anti-inflammatory shot

Manny Pacquiao only threw 429 punches to Floyd Mayweather's 435 on Saturday night, which is kind of a shocking number when you consider Manny's trademark aggression and go-for-broke style.

It appears there was a pretty good reason for Pacman's relative lack of volume.

Pacquiao suffered a right shoulder injury during training camp a few weeks ago, and was taking anti-inflammatory shots approved by the United States Anti-Doping Agency.

During the post-fight press conference, Pacquiao said he had torn something in his right shoulder, and according to Top Rank head honcho Bob Arum, the Nevada Athletic Commission did not allow Pacquiao to take the anti-inflammatory shot prior to the bout despite having previous knowledge of the injury. 

Arum was questioned in the press conference why he would allow an injured fighter to compete, but Arum countered that Pacquiao tweaked the injury in the third round which left him unable to effectively throw his right hand.

"We felt the (rehabilitative) work that was done on the shoulder duing training would give him the opportunity to use the right hand," promoter Bob Arum said. "We were disappointed when in the third round the injury kicked up again, but this is always the case in sport. ... He heals the injury, thinks he’s conquered it and it flares up again."

Although he wasn't able to freely throw his deadly right hook, Pacquiao still maintains that he won the fight, despite the 48 minutes of footage that likely proves otherwise.

When asked about Pacquiao's injury, Mayweather kind of brushed it aside, telling reporters that he came into the fight with injuries too, but didn't let that slow him down.

"Like I said before, I will always find a way to win," Mayweather said.
