UFC 152
UFC newcomer Roger Hollett was expected to face Matt Hamill, who returned from retirement, at the event. However, Hollett was forced out of the bout due to a contract dispute and replaced by Vladimir Matyushenko. Then, on September 11, 2012, Matyushenko pulled out of the fight after suffering a torn achilles tendon while training, and Hamill vs. Hollett was rebooked by UFC officials.
