Newly crowned UFC welterweight champion Johny Hendricks will undergo surgery to repair a torn right biceps he suffered two weeks prior to UFC 171.

Hendricks (16-2) claimed the vacant UFC welterweight title last weekend, defeating Robbie Lawler via unanimous decision at UFC 171 in Dallas.

On Wednesday, Hendricks confirmed to ESPN.com he went into the fight with a pre-existing injury. He expects to sit four to six weeks, before starting a rehab program.

"My last day of sparring, I threw a hook and felt it pop," Hendricks told ESPN.com. "At that point, I told myself, 'I'm done (sparring).'

"I had people working on my arm, doing active recovery on it, but it was already done. They were trying to help me prolong it and reassess after the fight. I didn't think it was that bad. I had to fight. I knew I wasn't going to let the UFC down like that. I was the main event. I said, 'Yeah, this sucks, but do I think I can win doing this, this and this?' I thought I could."

Hendricks is aiming for a fall return to the Octagon, possibly as late as November.

"They said six weeks (inactivity), but I'm the type of guy who is going to (work) every day, twice a day if they allow me," Hendricks said. "They told me four weeks when I had knee surgery and I was back in two, wrestling. I'm going to do what it is to keep me healthy, but also what it takes to get me back in the Octagon better and faster."
