UFC 137 has already gone through its share of turbulence. Diaz was St. Pierre's originally scheduled opponent, only to find himself removed from the main event after no-showing back-to-back press conferences in Toronto and Las Vegas. Condit was pulled from his co-featured bout with Penn to step into the main event. That left Penn without an opponent. The UFC decided not to release Diaz for his transgressions, and instead slotted him in against Penn in an attempt to ease him into the UFC's PR machine.
