Lions defensive tackle Ndamukong Suh once more found himself in the middle of controversy, and his availability for the Lions' playoff game for next week could be in doubt.

With 5:48 left to play, Rodgers hit Jordy Nelson for 15 yards and a first down to the Detroit 43. Suh brought the pressure. After the pass, Rodgers fell to the ground and Suh appeared to accidently back up and step on Rodgers' ankle. But then it appeared Suh took another step back on purpose and stepped on Rodgers again, before pushing off on Rodgers' lower leg and walking away.

"I didn't see the play, so I really don't know," Packers guard Josh Sitton said. "Aaron definitely wasn't happy. So we'll look at it, check it out and see what happened. But, his actions kind of speak for themselves."

Rodgers stopped short of calling Suh out, but he was clearly unhappy after the game.

"I don't know, we'll look at the film," he said. "(Suh will) probably say it was an accident, he was getting blocked into him (Rodgers). That's what (referee) Walt Anderson said. But we'll see.

"It was my calf and my ankle getting stepped on, so we'll see what happens."

McCarthy was asked if Suh, with a long-held reputation as a dirty player — was the dirtiest player he'd seen.

"Well, those are your words, first of all — dirtiest player I ever played against," McCarthy said. "But I'll say this, I didn't see it live, I didn't see it on the Jumbotron, but from what I'm told, I'm told it was ridiculous. There's no place for that. That's where I'm at with it. I don't understand it, frankly."

Peter King of Sports Illustrated reported on NBC that the NFL will investigate the incident.

Lions coach Jim Caldwell said he didn't see the play, but still believed it wasn't intentional. Packers right guard T.J. Lang had his back to Suh when he stepped on Rodgers, but could immediately tell his quaraterback wasn't happy.

There's a lot of history between Suh and the Packers, beginning when he stomped former Packers offensive lineman Evan Dietrich-Smith in 2011. He received a two-game suspension for the incident, which are still the only two games he's missed in his NFL career.

"Aaron looked upset and said that he felt like he stepped on his calf or something," Lang said. "I didn't really see it, but you know later in the game I was blocking him and he's a guy that likes to play through the whistle sometimes, and so I kind of matched his effort, and he got a little upset at me. I won't say what he was saying to me. That's not safe for work language."
