Detroit Lion Ndamukong Suh suspended, will miss playoff game

Detroit Lions defensive end Ndamukong Suh has been suspended by the NFL for stepping on the leg of Green Bay Packers quarterback Aaron Rodgers and will miss the team’s wild card playoff game in Dallas on Sunday, according to reports on the NFL’s website.

Suh was suspended for “a non-football act,” according to a tweet by NFL Media Insider, Ian Rapoport.

NFL vice president of football operations Merton Hanks explained the suspension in a letter to Suh, according to writer Marc Sessler.

"You did not respond in the manner of someone who had lost his balance and accidentally contacted another player who was lying on the ground. This illegal contact, specifically the second step and push off with your left foot, clearly could have been avoided,” the letter reads, according to Sessler. "You unnecessarily stepped on your opponent's unprotected leg as he lay on the ground unable to protect himself."

Suh, stumbled back and stepped on Rodgers' lower left leg while the quarterback was on the ground at the end of a play in the fourth quarter.

There was no penalty, and Rodgers said referee Walt Anderson told him he thought Suh was blocked into the quarterback.

Packers head coach Mike McCarthy didn't see the play, but heard enough from others to be unhappy with Suh.

"There's no place for that," McCarthy said. "I don't understand it, frankly."

Suh had cleared out of the locker room by the time reporters were allowed in after the game.

Lions head coach Jim Caldwell also said he didn't see the play but had it recounted to him.

"Don't think it was intentional. End of story," Caldwell said.

Suh can appeal suspension.
