Julius Peppers was tearing after Denver quarterback Jay Cutler when he was blatantly held. When there was no call, Panther coach John Fox ran onto the field to complain, pointing to the scoreboard, which was showing the replay.
After the Panthers stopped the Broncos, Fox talked angrily to two officials and then ran to Peppers on the bench and made a downward chopping motion. Next time you're held, do this, I think is what Fox was saying.
Be interesting to see how Peppers reacts if he's held again.
