During the second quarter of the Cleveland vs. Pittsburgh game, WR Antonio Brown broke free on a punt return. He only had one man to beat -- Browns P Spencer Lanning. Brown could have just ran left or right and probably had a touchdown, but instead, he decided to kick Lanning in the head:
Brown was flagged 15 yards on the play, but this should have been an ejection. Brown clearly intended to do what he did, and he should be hearing from the league this week.
