On Saturday night, Georges "GSP" St-Pierre, arguably the greatest fighter in UFC history and the promotion's long-standing welterweight champion, will make the long walk to the UFC Octagon for the first time in almost four years.
At the age of 32, after a dozen consecutive victories and nine straight successful title defenses, St-Pierre called it quits.
He returns to a different landscape.
The cage will still be 750 square feet. The rounds will still be five minutes in duration. One of the world's best fighters, middleweight champion Michael Bisping, will be standing across the cage to greet him.
