Baltimore Ravens safety Ed Reed has been fined $55,000 for his hit on New York Giants wide receiver Victor Cruz in Sunday's game.
An NFL spokesman confirmed Reed's fine for striking a defenseless player in the head and neck area.
Reed will not be suspended, according to a FOX Sports report.
Reed was penalized when he delivered a shoulder blow high to the upper body of the wide receiver.
Last month, Reed had a one-game suspension overturned but still had to pay a $50,000 fine for his hit on Steelers wide receiver Emmanuel Sanders.
A person familiar with the penalty says the NFL also has fined Panthers quarterback Cam Newton $21,000 for abusive conduct toward a game official.
The person spoke to The Associated Press on Thursday on condition of anonymity because the league hasn't announced the fine.
Newton shouted at and bumped referee Jerome Boger in the fourth quarter of Carolina's penalty-plagued 17-6 victory over the Oakland Raiders on Sunday.
Newton apologized after the game, saying: "The words that I said during the game were very disrespectful and I apologized to (Boger) during the game, but I'm going public and apologizing again. It was something in the heat of the moment."
Boger said he didn't feel the bump was enough to warrant an ejection because it "wasn't of a malicious nature."
