Cam Newton has received his second fine of the week for kicking an opponent.
The Carolina Panthers quarterback will be docked $10,000 (£6,200) for kicking Oakland Raiders defensive tackle Tommy Kelly in their game last Sunday.
The 23-year-old had already been handed a $21,000 (£13,000) fine for abusive conduct towards an official in the same game.
Teammate Greg Hardy also receives a fine for a hit on Raiders quarterback Carson Palmer.
The defensive end hit Palmer in the back with his helmet, resulting in the 32-year-old being unable to finish the game, and missing this Sunday's fixture.
