UFC 217 video: Watch the official trailer for Michael Bisping vs. Georges St-Pierre

Watch ‘Battle Cry’, the official UFC 217 trailer for the middleweight title fight between Bisping and GSP.

In just under a month, Michael Bisping will defend his middleweight championship against welterweight legend Georges St-Pierre at UFC 217.

The UFC dropped the official trailer yesterday, titled Battle Cry. Check out the video above.

Bisping, 38, stunned the world when he knocked out heavy favorite Luke Rockhold to win middleweight gold last year. Bisping, who stepped up on short notice, was submitted by Rockhold in 2014 but won the rematch in style, dropping the Californian with a left hook and following up with brutal ground and pound.

Bisping then went on to avenge his loss to old rival Dan Henderson, who knocked out the Brit with a nuclear overhand right at UFC 100. ‘The Count’ won the rematch via unanimous decision, officially defending his title in his former hometown of Manchester, England.

Bisping was expected to fight the winner of the interim middleweight championship bout between Robert Whittaker and Yoel Romero, but Whittaker -- who won the fight via decision -- sustained an injury and is expected to be out of action for the rest of the year.

That’s when the UFC confirmed that St-Pierre would challenge Bisping for the 185-pound title in November.

‘Rush’ retired from the sport in 2013 after defending is welterweight title nine times, beating Johny Hendricks at UFC 167. After spending almost four years on the sidelines, St-Pierre announced his official comeback earlier this year.

The Canadian fan favorite was initially scheduled to fight Bisping in the Summer, but UFC president Dana White decided to scrap the bout after claiming that GSP needed more time to prepare.

After news got out of Whittaker’s injury, White had the fight re-booked for UFC 217. The highly anticipated pay-per-view takes place next month, November 4, at Madison Square Garden in New York.
