Anthony Pettis is currently right in the thick of the UFC’s 155lb title mix, but unfortunately we won’t be seeing him back in the Octagon in the near future due to an injury.

The ‘UFC Tonight’ revealed last night on Fuel TV that Pettis is set to undergo surgery on the undisclosed injury which will keep him out of action for 8 weeks.

Pettis last fought at UFC 144 in February and his spectacular head kick victory against Joe Lauzon, added to a win last year over Jeremy Stephens, lead to rumors that he may have been on course for a rematch with current champion Ben Henderson who he defeated at the end of 2010 to claim the WEC lightweight title.

However, while UFC president Dana White initially appeared to be on-board with the idea, plans changed and a headlining fight at UFC On FOX 3 between Nate Diaz and Jim Miller will now establish the next No.1 contender.

That leaves Pettis somewhat in limbo, so perhaps it’s not the worst time to have to take an injury break.
