Georges St-Pierre has suffered a knee injury in training and will need at least a month to recover per Dana White. The main event on the card will now be Nick Diaz and BJ Penn, still scheduled for three rounds.
Condit has been pulled from the card, as well, and apparently will wait until GSP is healthy instead of taking another fight.
GSP has sprained his medial collateral ligament and apparently will be sidelined 4-6 weeks. The fight is going to be rescheduled for the 1st quarter of 2012 but no firm date is set.
