Less than three minutes into the game, Jackson made a 13-yard reception and was hit after the play by Eagles safety Malcolm Jenkins. Jackson stood up and shoved Jenkins, which earned him a 15-yard penalty for unnecessary roughness. Jenkins, it should be noted, wasn't a teammate of Jackson in Philadelphia -- he was signed from New Orleans in the offseason.
FOX's rules expert Mike Pereira points out, however, that it should have been Jenkins who drew the penalty, not Jackson for retaliating. (Click through to the tweet for a video of Pereira's analysis.)
Later in the game, Jackson caught an 81-yard touchdown pass and celebrated with a flapping motion, a clear dig at his former team.
Jackson reportedly told his Washington teammates he would "do anything to play" against his former team.
