Manny Pacquiao faces a potential lawsuit after failing to disclose a shoulder injury before his defeat by Floyd Mayweather.
Pacquiao will spend up to a year on the sidelines as he prepares to undergo surgery on his torn rotator cuff, an injury he suffered in training.
But the Filipino star could also be guilty of perjury after signing a pre-fight questionnaire without revealing he was hurt.
Sportsmail has obtained a copy of the document and although it shows that Pacquiao was taking several painkillers, the word ‘No’ is marked next to the question: ‘Have you had any injury to your shoulders, elbows, or hands that needed evaluation or examination?’
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’.
Under chapter 199 of the law of Nevada (NRS), ‘A person who, in a declaration made under penalty of perjury, makes a wilful and false statement in a matter material to the issue or point in question is guilty of perjury or subornation of perjury, as the case may be, which is a category D felony and shall be punished.’
The punishment for a crime of this nature is between one and four years in prison and a fine of up to $5,000 (£3,305).
Pacquiao could also be fined or banned by the Nevada State Athletic Commission.
The commission’ chairman Francisco Aguilar said that the state attorney general’s office will look at why the injury was not declared.
‘We will gather all the facts and follow the circumstances,’ he said. ‘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.
‘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.’
