Detroit Lions defensive tackle Ndamukong Suh was fined $100,000 by the NFL for his hit on Minnesota Vikings center John Sullivan during Sunday's game but won't be suspended, the NFL announced Tuesday.

The league said in a statement that NFL vice president of football operations Merton Hanks told Suh on Tuesday that he had been fined.

"Suh was penalized for violating Rule 12, Section 2, Article 5 (a), which prohibits blocks below the waist by players of either team after a change of possession," the league said in its statement.

Suh will appeal the fine, a league source told ESPN NFL Insider Adam Schefter.

The controversial play occurred during an interception return by Lions linebacker DeAndre Levy, who scored an apparent touchdown to give Detroit the lead. But the play was nullified because Suh was whistled for an illegal low block against Sullivan well behind the play. The Lions eventually won the game 34-24.

Suh restructured his contract for this season, changing his payment for 2013 into an $11.5 million signing bonus and a $630,000 salary. His salary puts his weekly checks at $39,375 for the Lions' 16 games, meaning he essentially lost money playing Sunday because of the $100,000 fine.

NFL Players Association executive director DeMaurice Smith tweeted Tuesday that he has reached out to Suh.

Several Lions players said Suh apologized to the team Tuesday and to Levy individually.

"He apologized to the team. It was sincere. We accepted it," running back Joique Bell said. "We all a family, and that's our brother. At the end of the day, we all we got. So, it was a good deal. Levy accepted it, so if he can accept it, everybody should be able to accept it."
