Georges St. Pierre left mixed martial arts at the height of his power a little less than four years ago and returns to a sport brimming with skepticism regarding his prospects for success.
St. Pierre will challenge Michael Bisping for the Ultimate Fighting Championship middleweight crown in the UFC 217 headliner this Saturday at Madison Square Garden in New York. There, he can join B.J. Penn, Randy Couture and Conor McGregor as the only fighters in UFC history to capture titles in two different weight classes.
