Moore received a penalty for roughing the passer after his helmet hit Mallett’s chest during the second quarter. Mallett appeared slow to get up after the play and trainers tended to him.
The Texans replaced Mallett with Brian Hoyer, who played the rest of the game.
Before exiting the game, Mallet was 7 of 10 for 50 yards.
The 25-year-old, who enters his third season in the NFL, has seen action in every game this season, recording five tackles so far.
Moore commented on the fine on Twitter on Friday.
