You may have missed it if you didn't watch all the way to the end of the Bengals' win against the Bills on Sunday.
But Buffalo defensive back Dean Marlowe was flagged for a punishing hit against Cincinnati tight end Mason Schreck as Schreck slid to the ground that the NFL may examine - and consider whether to assess a fine.
Can't stress enough that I'm NOT calling Dean Marlowe a dirty player. It just happens to be an excellent illustration of the new #nfl lowering the head rule. This used to be a "by the book" tackle but now possible grounds for ejection.
