The NFL fined Miami Dolphins defensive end Lorenzo Bromell $15,500 Thursday for his hit that broke Indianapolis Colts quarterback Peyton Manning's jaw last Sunday.
Bromell said he plans to appeal the fine.
The hit came in the fourth quarter with the Colts leading 24-20 and forced Manning out of the game for one play with a hairline fracture of the jaw and a bloodied mouth.
He was replaced by Mark Rypien, who fumbled a handoff.
The Dolphins recovered, setting up the game-winning drive.
Bromell said he didn't want to talk about the fine as he walked off the practice field, noting, "If I say what I want to say, I'll be fined again."
"It wasn't a late hit," coach Dave Wannstedt said. "They have to determine if it was intentional or not.
"I didn't think it was. I thought he was making a great effort to get to the quarterback."
Manning is expected to play Sunday against New Orleans. Miami plays the New York Jets.
