Reed was fined $55,000 for hitting New York Giants receiver Victor Cruz in the head and neck area during the Ravens' 33-14 win while Newton was fined $31,000 for two incidents in the Panthers' 17-6 victory over the Oakland Raiders.
He was fined $21,000 for abusive conduct towards a game official and $10,000 for kicking Oakland defensive tackle Tommy Kelly after being sacked and the play was over, the league said.
Newton yelled at referee Jerome Boger and bumped into him after a play. He later apologized.
Boger, who penalised Newton for unsportsmanlike conduct, said he did not eject him because he did not believe the contact was malicious.
New England Patriots defensive lineman Vince Wilfork was also docked $30,000 for striking Jacksonville offensive lineman Steve Vallos in the head with his forearm in last Sunday's game. (Reporting by Gene Cherry in Salvo, North Carolina; Editing by Greg Stutchbury)
