Detroit Lions defensive tackle Ndamukong Suh is facing potential discipline from the NFL.
The league is reviewing Suh's play against Cleveland.
Suh led with his helmet when he hit Browns quarterback Brandon Weeden after he threw a pass in Sunday's game. The hit that wasn't penalized was shown on a video posted on NFL.com on Tuesday as vice president of officiating Dean Blandino said, "Why don't we look at it some more?" in the league's officiating command center.
Suh was fined $100,000 for an illegal block on Minnesota Vikings center John Sullivan during an interception return in Week 1. He lost an appeal last week, upholding the largest fine in NFL history for on-field conduct, not including money lost by players due to suspension.
