UFC 137 is just over two weeks away, so to get your blood pumping, check out the recently released extended trailer, which features not only a look into the upcoming welterweight title fight between Georges St. Pierre and Carlos Condit, but a welterweight clash between B.J. Penn and Nick Diaz and the heavyweight slug fest between Cheick Kongo and Matt Mitrione. Featuring 12 fights including Mirko Cro Cop vs. Roy Nelson, Donald Cerrone vs. Dennis Siver, and Scott Jorgensen vs. Jeff Curran, UFC 137 is looking like on hell of a card, barring any last minute injuries.

A few notes:

With four consecutive wins including back-to-back first-round knockouts of Dan Hardy and Dong Hyun Kim, Carlos Condit is one of the hottest contenders in the UFC welterweight division. But to be a legend, he’ll have to start beating legends. The Natural Born Killer will get an opportunity to do just that at UFC 137: St. Pierre vs. Diaz (October 29th, Las Vegas), where he’ll face former lightweight/welterweight champ BJ Penn in the co-main event. With just one victory in his last four fights, Penn needs to make a statement against the young up-and-comer to prove that he’s not ready to be put out to pasture just yet.

But forget about what this fight “means.” These are two guys who go for the finish every minute of every round, and Penn vs. Condit is guaranteed to be a thriller. As the video reminds us, 96.3% of Condit’s wins come by stoppage — and Penn has still yet to be knocked down, despite a 10 year career that saw him fight across four different weight divisions. That’s kind of insane. Condit is currently a slight favorite with the oddsmakers. Sound about right to you?
