A knee injury has forced lightweight Gray Maynard out of a December 29 tilt with Joe Lauzon at UFC 155, costing the card one of its most anticipated bouts. Fortunately, the UFC has found a more than adequate replacement for Maynard in the form of Jim Miller.

UFC officials confirmed the change earlier today. The match-up is scheduled to take place on PPV alongside other fights such as Phil Davis-Forrest Griffin, Chris Weidman-Tim Boetsch, and Junior dos Santos-Cain Velasquez.

According to a report from MMAWeekly citing Maynard’s manager, “The Bully” suffered a tear to his “medial and lateral meniscus”, will require surgery, and is expected to need about a month to recover before resuming his training regiment.

Miller will be looking to get back on track after suffering his first stoppage in May, falling victim to a Guillotine Choke courtesy of top contender Nate Diaz. The 21-4 Miller had won eight of nine fights entering the bout including success against Mac Danzig, Mark Bocek, and Melvin Guillard.

With 22 finishes in 22 career wins, Lauzon should certainly serve as a stiff test for Miller. The 28-year old was last seen submitting Jamie Varner in August at UFC on FOX 4.
