Sherdog.com reports that a knee injury suffered during training has forced UFC welterweight champion Georges St. Pierre out of his main event title defense against Carlos Condit at UFC 137 which is only a little over a week away. According to GSP’s camp, the champ only suffered a serious sprain and nothing is broken. St. Pierre could feasibly be good to return to the octagon in as little as a couple months, but that is not an official timeline.

In lieu of this bad news the UFC has decided to have Condit sit out and wait for GSP rather than give him replacement fight which would put his #1 contender status at risk. Luckily for the UFC the 137 card had a co-main event that was still worked as a main event, so the new main event is now a three round fight between B.J. Penn and Nick Diaz, with the winner likely positioning themselves next in line for a welterweight title shot after St. Pierre and Condit are able to get their fight done. Normally losing the main-event of a fight card this close to the day of the event would be a terrible thing, and while its still a bad thing, this card doesn’t suffer nearly as much as other’s would have thanks to having fights like Diaz vs. Penn, Siver vs. Cerrone, Cro Cop vs. Nelson, Vera vs. Marshall, and more(not to mention that some of these amazing fights are on the preliminary card, which can be seen without having to order the pay-per-view.
