After all, he’s done it before. Former long reigning welterweight champion Georges St-Pierre first walked away from fighting back in 2013, after a controversial split decision win over Johny Hendricks. And his time in MMA seemed entirely finished in the years that followed. He hosted a TV show about dinosaurs, had a notable role in Captain America: The Winter Soldier, and even championed an MMA unionization effort (briefly).
It was something of a shock when GSP ended his nearly four-year hiatus from competition to take on then-middleweight champion Michael Bisping at UFC 217. Fourteen minutes and twenty three seconds later, and St-Pierre added a second belt to his collection.
