Georges St-Pierre will defend his UFC welterweight title against American Josh Koscheck on Dec. 11 in his hometown of Montreal.
UFC president Dana White confirmed the news to The Canadian Press.
The mixed martial arts card will be the second in Montreal this year, following UFC 113 on May 8 at the Bell Centre. The UFC also made its debut in Vancouver in 2010 with UFC 115 in June.
The December card, expected to be UFC 124, will mark the second UFC title fight for GSP in Montreal. He won his 170-pound championship back from Matt (The Terror) Serra at UFC 83 in April 2008 when the UFC first came to Canada.
St-Pierre (20-2) beat Koscheck at UFC 74 in a non-title defeat in April 2007. That fight followed GSP's loss in his first title defence against Serra at UFC 69.
The 29-year-old from Montreal has won seven straight since that defeat. His last four wins have come in title defences against Jon Fitch, B.J. Penn, Thiago Alves and Dan (The Outlaw) Hardy.
St-Pierre and Koscheck recently completed filming as rival coaches on Season 12 of "The Ultimate Fighter" reality show. The TV series debuts Wednesday, Sept. 15, and will lead into the live card in December.
Koscheck (17-4) has won his last three fights against Frank Trigg, Anthony (Rumble) Johnson and Paul (Semtex) Daley.
The California-based fighter, who relishes playing the villain, has been talking up the GSP fight on Twitter.
"Shock time is coming!!!!!" read one tweet.
"We got a frenchy's ass to kick," read another.
St-Pierre was unimpressed.
"He's not the only guy who has said stupid stuff like this to me, I'm used to it," he said Aug. 12 on a visit to Toronto. "And I'm smart enough to fight him smart and not fight him with emotion and make a mistake.
"But when it's time to punch him, just the little extra motivation I'm going to have at the end of the punch to twist my knuckle into the head, it will be good thing. It will give me an extra power edge."
St-Pierre is currently training in New York.
