St-Pierre Injured: Diaz vs. Condit at UFC 143

Match-ups change on a dime in mixed martial arts, and the pairing of Georges St-Pierre and Nick Diaz has suffered its second blow. Slated to fight each other at UFC 143 on Super Bowl weekend, GSP has been knocked out of the bout with a “blown ACL.”

UFC president Dana White tweeted the news on Wednesday, identifying St-Pierre’s injury, and noting that he will be out for about 10 months due to the injury.

White also confirmed that Carlos Condit would be slotted in his place to face Nick Diaz for the interim UFC welterweight title.

This marks the second time the bout between St-Pierre and Diaz has been derailed. The first time was UFC 139, when Diaz missed a couple required public appearances, raising the ire of UFC officials, who pulled him from the bout and replace him with Carlos Condit.

St-Pierre, however, suffered a minor knee injury in training prior to the bout, leaving officials no choice but to elevate the UFC 139 co-main event between Nick Diaz and B.J. Penn to main event status, rescheduling GSP and Condit for UFC 143.

Diaz went on to defeat Penn. White then made the call to put Diaz back in the title picture, setting him up to challenge St-Pierre at UFC 143 on Feb. 4 in Las Vegas, moving Condit aside to face Josh Koscheck on the same night.

Now, with GSP having to bow out once again, the UFC is matching up Diaz and Condit in the UFC 143 main event for an interim belt.
