Fuel TV’s Glazer unsure of how UFC’s St-Pierre will respond after torn ACL

Georges St-Pierre is a favorite of more than 3-to-1 at most sports books. But Fuel TV analyst Jay Glazer is unsure of how the welterweight phenom will fight Saturday at UFC 154 against Carlos Condit for one reason.

“I can’t predict, because I don’t know how the knee is gonna be,” Glazer told The Post.

St-Pierre hasn’t fought since April 2011 due to a torn ACL. He comes into this matchup as the UFC welterweight champion and arguably the company’s biggest star. Condit, though, has been the top guy in the 170-pound division since GSP has been out, beating Nick Diaz in February for the interim title.

It’ll be the knee that determines who wins and loses, Glazer says.

“I just don’t know how GSP is gonna respond to the knee,” said Glazer, who is also a top NFL analyst for FOX Sports. “Just dealing with football I know there’s a ton of guys who have had tbat problem. [Minnesota Vikings running back] Adrian Peterson thought he was back and he was back. Other guys are different. [Raiders quarterback] Carson Palmer insisted he was back, but his brain would just make him hesitate a second. Your brain makes you hesitate a lot. Everybody responds different.”

Glazer got a more intimate view of St-Pierre when he sat down for Fuel TV’s welterweight roundtable with GSP, BJ Penn, Matt Serra and Renzo Gracie. Part 2 of that segment will air Thursday at 11 p.m. What caught Glazer’s attention the most is how nervous St-Pierre, one of the UFC’s greatest champions ever, gets before fights.

“While he’s coming down to the cage he’s almost playing a role to convince himself that something else is happening,” Glazer said. “I would have thought he would have been one of the more relaxed guys. It’s amazing.”

The NFL and MMA insider already knows Condit well. He has trained with him in the past and calls him one of the nicest guys you’ll ever meet — until he steps into the Octagon.

“Then he turns into the nastiest, most ornery SOB you’ve ever been around,” Glazer said.

Glazer says he expects the fight to be “fantastic,” because “both guys can take the fight anywhere it needs to go.”

As far as who will win, Glazer can’t make a pick because of St-Pierre’s knee.

“You get back physically, but I can’t tell you how a guy is goiong to respond mentally,” he said.
