Pacquiao could face suspension for failure to disclose shoulder injury

Manny Pacquiao could face disciplinary action from the Nevada Athletic Commission after not disclosing that he had a shoulder injury before his welterweight unification bout with Floyd Mayweather, Jr. last Saturday in Las Vegas.

Nevada Athletic Commission chairman Francisco Aguilar says the Nevada attorney general's office will investigate why Pacquiao checked "no" on a questionnaire asking whether he had a shoulder injury before the two fighters weighed in on Friday.

Pacquiao ended up losing a unanimous decision to Mayweather and did not reveal that he was injured until after the bout.

He said he asked the Nevada Athletic Commission if he could receive an anti-inflammatory shot for his shoulder, but that request was denied.

Pacquiao will reportedly have surgery to repair a torn rotator cuff in his right shoulder and could be out for the next 8-10 months.

“We will gather all the facts and follow the circumstances," Aguilar said to the Associated Press. "At some point we will have some discussion. As a licensee of the commission you want to make sure fighters are giving you up-to-date information."

Pacquiao faces possible sanctions, which could include fines or a suspension for not telling the truth on the form.

"It's not just the fact he didn't fill out the question completely, it was that he wasn't honest and they didn't tell us a month ago when he had the shoulder injury," Nevada Athletic Commission executive director Bob Bennett said. "They're not obligated to, but two hours before the fight they wanted a shot that's a pain killer in essence. That put us in a very precarious position."

Mayweather told ESPN’s Stephen A. Smith earlier in the day that he would give Pacquiao a rematch in about a year.
