It turns out it was an elbow injury that forced Mark Munoz out of his number one contender’s match with Chael Sonnen at UFC on FOX 2 next weekend. Munoz described the injury in more detail along with confirmation that it will require surgery on Twitter earlier today.

For those that r wondering. Injury on Fri sparring causing bone spurs to dislodged in my joint causing locking & pain. Surgery on Thursday.

The spurs dislodged from my bone and into my joint causing bone chips to float around in the joint space.

The injury may require surgery, but it won’t keep him out of action for too long. Munoz only expects to be out for 4-6 weeks before he can resume training.

The downside of course is he missed his opportunity to earn a title shot, but hopefully he’ll still get the chance later this year when he returns.
