Two Las Vegas residents filed a class-action lawsuit Tuesday seeking more than $5 million in damages from Manny Pacquiao.

The lawsuit comes two days after Pacquiao admitted a shoulder injury hindered his performance in his defeat to Floyd Mayweather Jr over the weekend.

“The allegations in this lawsuit are demonstrably false,” Top Rank’s attorney Daniel Petrocelli told ABC News. “There are documents that explicitly show the medications that Manny was using to treat his shoulder and it was fully disclosed with USADA, which we contracted for this fight.”

However, Nevada Athletic Commission chairman Francisco Aguilar said that the state attorney general's office will investigate why Pacquiao denied having shoulder injury on a pre-fight questionnaire obtained by True Ink Boxing.

"We will gather all the facts and follow the circumstances,” Aguilar told 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.”

The bout’s pay-per-view revenues may surpass $300 million and betting experts believe $60 million-$80 million was waged on the fight.

Pacquiao can face a fine or suspension for wrongly filling out the medical forms. He will undergo surgery later this week to repair the “significant tear” in his rotator cuff.
