Pacquiao to undergo surgery?

Orthopedic surgeon Dr Neal ElAttrache has  told ESPN.com that Manny Pacquiao will undergo surgery later this week to repair a ''significant tear'' in his rotator cuff.

ElAttrache examined Pacquiao last Monday at his Kerlan Jobe Orthopedics office in Los Angeles after the Filipino revealed immediately after his loss to Floyd Mayweather Jnr that he was hampered by an injury to his right shoulder.

A little more than two hours before the fight, Pacquiao's corner asked Nevada regulators if he could be given a shot of Toradol, an anti-inflammatory. 

Now the Filipino  could face disciplinary action from Nevada boxing officials for failing to disclose a shoulder injury before the fight.

Nevada Athletic Commission chairman Francisco Aguilar said last Monday that the State Attorney General's office would look at why Pacquiao checked ''no'' a day before the fight on a commission questionnaire asking if he had a shoulder injury.

''We will gather all the facts and follow the circumstances,'' Aguilar 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.''

Pacquiao could face a possible fine or suspension for not answering the question accurately on a form he filled out just before Friday's weigh-in. He went on to lose a unanimous decision to Mayweather in the richest fight ever. — ESPN
