Manny Pacquiao could be prosecuted for perjury after failing to disclose shoulder injury

Manny Pacquiao faces potential prosecution for perjury after it emerged that he failed to disclose a shoulder injury ahead of the 'Fight of the Century' with Floyd Mayweather.

In the pre-fight medical questionnaire, Pacquiao answered 'no' to the question about whether he had suffered any shoulder injuries.

But after the fight in Las Vegas, the Pacquiao camp complained of a shoulder injury inhibiting the Filipino fighter and it was confirmed on Monday that he will undergo surgery for a damaged rotator cuff.

And now according to reports in the US, the non-disclosure has sparked an investigation by the Nevada authorities - since by signing the document, both Pacquiao and his adviser Michael Koncz "hereby swear under penalty of perjury, that the above information is true and correct to the best of my knowledge".

“Disclosure is a big thing for us, and honesty,” Cisco Aguilar, the Nevada Athletic Commissioner chairman told the Daily News on Monday. “The commission at some point will have to discuss (Pacquiao's medical questionnaire). I've got to run through the process with the (Nevada) Attorney General (Adam Laxalt). But they do sign that document under the penalty of perjury.”

“The medications he was taking were disclosed on his medical questionnaire, but not the actual injury.

“This isn't our first fight. This is our business. There is a process, and when you try to screw with the process, it's not going to work for you.“

 If found guilty of perjury, Pacquiao could face between one and four years in prison and a fine of up to $5,000 (£3,305). He could also be fined or banned by the Nevada State Athletic Commission.
