UFC middleweight Tim Kennedy is set to take to the Octagon again in a little over a month when he’ll serve as one half of the headlining duo at UFC Fight Night 31. The card is particularly important to decorated military veteran Kennedy, as the show comes with a Fight for the Troops tag and is unfolding at Fort Campbell in Kentucky. Unfortunately, Kennedy’s original opponent – Lyoto Machida – was pulled out of the fight to fill a vacancy created by an injury to Michael Bisping, leaving the Army Ranger without an adversary at the event. That being said, who should the UFC consider as a replacement? (Photos by USA Today Sports Images)
