Bengals safety Shawn Williams was ejected for a huge helmet to helmet hit on Colts quarterback Andrew Luck. 

Luck was scrambling for a first down and on his way to the ground when Williams lowered the boom.  He didn’t seem at all fazed by the hit, as he immediately popped up and gave his sideline a thumbs up.

You can’t put a shot on a guy like that in today’s NFL.  Williams has to know better than that.  Luck was fortunate he was able to avoid an injury on this hit.
