The NFL fined Patriots safety Patrick Chung and Broncos linebacker Von Miller $7,500 each for actions during last week's divisional playoff game at Gillette Stadium.
Both were fined for unnecessary roughness.
Via a league spokesman, Chung's fine came when "specifically, on a run play he struck an opponent late."
In the third quarter, Chung was flagged on a second-and-4 run by Willis McGahee.
For Miller, his penalty came when "specifically, on a special teams play, he struck an opponent late."
That was in the fourth quarter, when the rookie shoved Dan Connolly at the tail end of Tom Brady's punt.
