I’ve not seen a definitive answer from anyone. Best guess I’ve seen was jawing at a ref.
He had an earlier penalty and then was on his back after a play with a 9er lineman on top. He took exception to a little rough play after whistle and gave a little punch. Penalty 2 for i sportsmanship and he’s outta there. 25 penalties for over 270 yards between the two teams. Tough reffing…
Seems like a lot of those were within the last 7-8 minutes.
