GSP injured and off UFC 137, Diaz VS Penn upgraded to main event

Big news came out of the UFC world yesterday when Dana white announced via twitter that next weekend’s UFC 137 has just undergone a major change of plans.

DFW, who is currently in New York, tweeted that welterweight champion Georges St. Pierre injured his knee and will be out for a few months. His opponent, Carlos Condit, will sit out UFC 137 as well and wait until GSP is healed for them to fight for the title. In lieu of this incident, BJ Penn VS Nick Diaz has been upgraded to the main event, which is ironic since the match was originally supposed to be GSP VS Diaz until Diaz no-showed two press conferences and pissed off White royally.

GSP completes the list of UFC champs who have been injured and forced to withdraw or delay matches in 2011. Bantamweight champion Dominick Cruz is currently rehabbing a broken hand that required surgery following his main event win over Demetrious Johnson at UFC Live: Cruz vs. Johnson on October 1. Featherweight champion Jose Aldo suffered a training injury to his back that forced him out of a planned UFC 125 title defense against Josh Grispi last November. Lightweight champion Frankie Edgar broke two ribs before his UFC 130 bout with Gray Maynard in May.

Middleweight champion Anderson Silva hurt his shoulder while training for his UFC 134 bout with Yushin Okami, but fought the match anyway. Unfortunately, he is unable to compete until next year while he recovers. Light heavyweight champion Jon Jones tore a ligament in is hand and was forced to pull out of his UFC 133 match against Rashad Evans this past August. Lastly, Heavyweight champion Cain Velasquez hurt his shoulder during his UFC 121 title win over Brock Lesnar last October and has been out since then, although he will be in action in a matter of months to face the new number one contender for his belt.
