With 4:45 to go in the third quarter, Harrison came untouched up the middle of the line on a Pittsburgh blitz. The linebacker drove Fitzpatrick into the ground, and Harrison was flagged for leading with his helmet.
Harrison stomped his foot on the ground following the play.
"It's not going to change the way I play," said Harrison, who's already been docked $100,000 this season. "There was nothing wrong about the play."
Harrison recently was called to the NFL office in New York regarding how rules designed to protect players from injury are being enforced.
