What happened to Manny Pacquiao's shoulder?

Manny Pacquiao says his right shoulder hurts from an injury, and that his chances of a fair fight were sabotaged.

How did it happen?

Natashya Gutierrez reports.

A day after his unanimous decision loss to Floyd Mayweather Jr, Manny Pacquiao says he was sabotaged on fight night.

Pacquiao faces reporters, his right arm on a sling, and admits they considered postponing the fight after he injured himself in sparring 3 weeks before the bout.

But he says his team decided to go on with the fight.

MANNY PACQUIAO, BOXER: We all talked. Freddie, even Bubuy, Bubuy even cried... if I can't, we talked about it. But if it heals, if it recovers, its okay, let's just not use it (in training) then on the night of the fight, it will be injected with the numbing agent. It's not a steroid but its legal here, for numbing. The problem is we were sabotaged.

Pacquiao says he was not allowed to take the painkillers for his shoulders on fight night even if they submitted the form required and it is legal in Las Vegas.

He says they even held back on his supplements on water - for this first time in his career.

MANNY PACQUIAO, BOXER: We filled it out but also I’m so disappointed because for the first time in my boxing career, more than 20 years, they hold my vitamins, they hold my water (from) the dressing room. This is new.

He then goes on to say that Mayweather knew about his injury, which is why Mayweather was pulling his arm during the fight.

MANNY PACQUIAO, BOXER: Did you see when he was pulling my arm? Because he knew. He was pulling it, did you see? Because he knew (about my injury)

The Nevada State Commission says it barred Pacquiao from taking injections because of its 6-hour lasting effect, but denied knowing about Pacquiao’s shoulder injury.

NATASHYA GUTIERREZ, REPORTING: The Filipino fighter wants a rematch with his opponent. He is convinced he can beat Mayweather if he were at 100% - the question is will he get that chance?

Pacquiao says his shoulder started to hurt in the 4th round, making it hard for him to punch the way he wanted.

But Pacquiao also says he does not want to make excuses about his loss.

MANNY PACQUIAO, BOXER: I wasn’t 100% ready for last night because of this shoulder but I don’t want to use that complaining that I lost the fight. I’m just accepting the fact that I lost.

Pacquiao is set to have an MRI in Los Angeles to make sure he does not need surgery for his shoulder.

Asked about Pacquiao’s injury after the fight, Mayweather only said fighters get injured in training all the time, but must find a way to win.
