UFC - Georges St-Pierre Injury Update

According to Dana White's Twitter page, reigning UFC Welterweight Champion Georges St-Pierre is pulling out of his scheduled UFC 137 title fight due to a knee injury. While this is a major disappointment for UFC fans and for Carlos Condit especially - the injury doesn't appear to be severe and the fight will be rescheduled to take place a couple months from now. Fighting in the main event instead will be B.J Penn against Nick Diaz for a 3 round bout. I've heard a couple people say St-Pierre is shook and is ducking the fight, to you I say go refill your prescription. Condit's recent TKO streak is intimidating, sure, but GSP would have to be lacking a lot of focus to get caught like that. Who's your money on?
