It's official - the UFC will be returning to Canada in September. This isn't exactly huge news, since Zuffa stated last year that there would be an event in Toronto in September, but now UFC 165 is set for the 21st in the Air Canada Centre. UFC Tonight tweeted the confirmation to the masses:
No fights have been announced for the card as of yet. This is the fourth event in Toronto, and the 14th overall in Canada. The last event in the ACC was UFC 151, where Jon Jones defeated Vitor Belfort in the main event. That show drew a disappointing gate of 1.9 million. Jones defended against Lyoto Machida in the second Toronto event at UFC 140.
It's possible that Georges St. Pierre could defend the UFC welterweight title against Johny Hendricks on the show, but that's all up in the air right now. After UFC 158, Dana White stated that UFC CEO Lorenzo Fertitta wanted GSP to fight in Vegas next, but who knows. It's a good fit for a main event of a Canadian card, but GSP has fought on home soil four times in a row now.
As for other possible title matches on top, it's tough to figure out. The UFC heavyweight title is being defended in two weeks, so it's conceivable it could be defended again in September. Jon Jones just defended his light heavyweight title at UFC 159, but there are no set challengers right now and he fought in Toronto the last two times they were there. Anderson Silva vs. Chris Weidman is in early July; Jose Aldo is defending his featherweight title against Anthony Pettis in August; and Renan Barao is defending in mid-June. In addition to that, the flyweight title is up for grabs in late July. So it seems like it'd be down to heavyweight, light heavyweight, welterweight, or possibly lightweight.
I'm sure we'll find out soon enough.
