Georges St-Pierre's title defense against Josh Koscheck will take place on Dec. 11 at the Bell Centre in Montreal, Quebec, Canada, UFC president Dana White confirmed with MMA Fighting Monday.
UFC 124 will happen at the end of the 12th season of The Ultimate Fighter, which premieres on Spike TV on Sept. 15. St-Pierre and Koscheck will serve as opposing coaches on the show.
The event will mark the second time the UFC comes to Montreal this year. UFC 113 also took place in Montreal.
St-Pierre has only fought once before in his hometown as a member of the UFC roster. He defeated Matt Serra to regain his welterweight title in April 2008 at UFC 83.
The UFC has since held two other events in "La Belle Province": UFC 97 in April 2009 and the aforementioned UFC 113 in May 2010.
St-Pierre defeated Koscheck at UFC 74 via unanimous decision in a non-title fight. His most recent successful title defense came against Dan Hardy at UFC 111.
Since losing to Paulo Thiago at UFC 95, Koscheck has won three in a row. His most recent win actually took place in Montreal when he defeated Paul Daley at UFC 113.
Koscheck will no doubt enter the cage on Dec. 11 as a major villain since he is fighting the hometown favorite and also took shots at the Montreal Canadiens following his win over Daley.
