Former UFC lightweight contender Gray Maynard has successfully undergone knee surgery. Now, “The Bully” will begin the long road back.

Maynard was originally set to face Joe Lauzon at UFC 155, but Jim Miller will take his place. Maynard is expected to be away from training for 3-to-5 weeks, and is hoping for an early 2013 return to the Octagon.

The former Michigan State University standout defeated Clay Guida earlier this year via decision.
