Earlier in the week the Ultimate Fighting Championship announced that a scheduled fight between Josh Thomson and lightweight champ Anthony Pettis had been postponed, due to the latter being injured. Now the newly crowned champion has revealed that his injured knee could require surgery.

While speaking to the Milwaukee Wisconsin Sentinel Journal recently, Pettis disclosed that he has a torn posterior cruciate ligament and that further:

“We’re thinking about operating,” Pettis said. “Most doctors don’t operate on PCLs, so no one has a clear answer at this point. I’m going to L.A. after my brother’s fight to get another opinion.”

“If I do need surgery, the time frame is four to six months off. If we decide to rehab, it’s another four to six weeks. I’m hoping for no surgery, but I don’t want this to be something that keeps happening.”

UFC President Dana White recently relayed to MMA Fighting.com that he believes the 26 year-old will require surgery. As a result, Thomson will looked be booked to fight in the interim. Thomson and Pettis had been scheduled to fight December 4th at UFC on FOX 9.

Pettis, who submitted Benson Henderson in August to become champion, has suffered several knee injuries in recent months. If the renowned fighter does undergo surgery then his first title defense likely won’t take place until mid 2014.
