GREEN BAY, Wis. — Chris Canty is fine. Good enough to laugh about his injured knee in the postgame locker room and relieved enough to take a swipe at the Packers fans who booed him when he went down with what they believed was a fake injury.

"I heard that, I heard that," the Giants' defensive tackle said with a grin after the team's 37-20 upset victory in the divisional playoff game today. "The fans pay their money, they're entitled to cheer as they see fit or boo as they see fit. It's unfortunate they won't be able to cheer next week."

Canty seemed to think he had suffered a significant injury at a really bad time. He also needed help getting off the field. But after being examined by team doctors, he was cleared to return.

“Just got a little shaken up there at the end but it happens, it’s football,” Canty said. “I’m a hundred percent, I’m ready to go next week.”

Canty said he let his teammates know right away he’d be okay. But in the meantime, Packers tight end Jermichael Finley was agreeing with the fans by saying Canty had taken a dive to slow the Packers’ momentum. (They had gone 60 yards in eight plays, thanks in part to a questionable roughing-the-passer penalty on Osi Umenyiora.)

Ironically, Deon Grant got into a shoving match with Finley. Grant took a dive in the Week 2 victory over the Rams and was the subject of scrutiny for much of the next week.

After the game, Grant said he lost his cool.

“I have to go on air and apologize to (Finley),” he said. “He was mad, thinking (Canty) was faking and I got at him like, ‘You don’t say nothing unless you know for a fact the guy is faking.’

“But I took it too far because he calmed down and I kept going and he walked toward me to talk. I shoved him first.”

Fox showed the shoving match but also replayed Grant and Finley hugging it out.

“I had to go to him as a man in good sportsmanship and tell him I was dead wrong,” Grant said. “I was out of line and I took it too far.“

CB Aaron Ross, a Texas native, had cramps in 30-degree weather.

“Man, that’s crazy,” Ross said. “I had to come in and get an IV. I couldn’t believe that.”

Ross and Grant both kept going in and out of the game in the third quarter. Grant had a head injury, though he passed all concussion tests.

“I’m gonna pass that every time,” Grant said with a grin.

Still, he was clearly hurting at least a little bit. “You know how I am. This is how I was bred,” he said. “We sign up for this game. We play the game with pain.”

DE Osi Umenyiora has gone from an ugly contract situation to being a content member of the team who has racked up 12 sacks in 11 games.

“It feels good, man,” he said. “I love these guys, man. I don’t even know how to explain it. I’m just so happy to be playing with a team like this. These D-linemen, it’s just fun. I’ve never had this much fun before.”

WR Victor Cruz appeared to suffer a knee injury in the second half but said he merely took a shot to the quad and would be fine.

VP of player evaluation Chris Mara wasn't with the team on the trip. He was attending the Golden Globe Awards. His daughter, Rooney, was nominated for best actress in a drama.
