UFC middleweight champion Anderson Silva will meet Ultimate Fighter alumni Stephen Bonnar in a light heavyweight bout in the night's main event.
UFC featherweight champion Jose Aldo was set to defend his title to former lightweight champion Frankie Edgar in his first bout at 145lbs. On Sept. 11, 2012 UFC president Dana White announced Aldo was forced to withdraw from the title bout after suffering a foot injury.
Coincidentally, a co-main event bout between light-heavyweights Quinton 'Rampage' Jackson and Glover Teixira was also cancelled after Jackson suffered a training injury to his elbow.
