Georges St-Pierre is back to defending the UFC welterweight title with regularity and will attempt to do so again in the UFC 158 main event against archrival Nick Diaz.
Diaz has been calling out St-Pierre for some time and will finally get his chance to challenge the Canadian titleholder despite losing in his most recent appearance against Carlos Condit.
St-Pierre and Diaz had been booked to fight in the past, but injuries and Diaz's refusal to appear at media-related events led to the delay in the matchup coming to fruition.
Johny Hendricks is widely considered a more deserving top contender than Diaz and will meet Condit in the UFC 158 co-main event. Should Hendricks beat the former interim champion, it would appear likely that he'll be next in line for a fight with the winner of the bout between St-Pierre and Diaz.
Another 170-pound contest between Jake Ellenberger and Nate Marquardt will be featured on the UFC 158 main card. Marquardt will be returning to the Octagon for the first time since leaving and becoming Strikeforce welterweight champion, a title which he lost in his latest fight against Tarec Saffiedine.
Saturday's event will take place at the Bell Centre in Montreal. On Friday, the fighters will hit the scales at 4 p.m. ET. Video of the weigh-ins will be streamed live on the above video player.
