UFC welterweight champion Georges St-Pierre has suffered a torn ACL that has forced him out of the UFC 143 main event against Nick Diaz, who will now face Carlos Condit for the interim 170-pound title at the Feb. 4 event in Las Vegas.
UFC President Dana White announced the news on Twitter on Wednesday.
St-Pierre (22-2) will be out at least 10 months to recover from the knee injury and hasn’t defended his title since topping Jake Shields at UFC 129 in April. Another knee injury forced St-Pierre out of an October fight with Condit, who moved into the main event after Diaz was pulled for no-showing several press conferences.
Diaz (26-7) dominated former champion BJ Penn in the new UFC 137 main event to earn the next shot at St-Pierre ahead of Condit (27-5), who was scheduled to fight Josh Koscheck in UFC 143’s co-main event in his first fight since stopping Dong Hyun Kim in the first at UFC 132 in July for his fourth-straight win.
It is not yet known whether Koscheck will remain on the UFC 143 fight card or who he would face if he does.
