Georges St. Pierre (23-2) shook off a year and a half of inactivity by defeating Carlos Condit (28-6) by unanimous decision in Montreal on Saturday night to defend his UFC welterweight title.

A knee injury kept GSP out of the cage for that period, but he showed he still had the tools to win his return fight against the tough Condit, who pushed the 31-year-old hard over five bloody rounds. After the final bell the three judges scored the fight 49-46 and 50-45 twice in favor of St. Pierre.

"People talk about ring rust, I definitely know what it is now," St. Pierre told Joe Rogan in the octagon afterwards. "Credit to Carlos, he gave me my toughest fight."

Condit's best moment came in the third round when he floored GSP with a high kick, but he could not end the fight.

"I thought I had him. He was still coherent and I was trying to get in there, put some leather on him and finish off the job, but he did a good job of recovering," he told Rogan.

With UFC middleweight Anderson Silva ringside to watch the fight, all eyes now turn to a possible super fight between the Brazilian and GSP.

St. Pierre said he would need to take some time off before thinking about a possible Silva fight, but UFC President Dana White was adamant post fight that Silva and St. Pierre would be getting it on as early as next May. Check out White's take on the night here:
