If this was a regular season game Kupp gets taken off the field for observation after that head shot, correct? But Super Bowl is more important than player health.
Edit: Also a procedural question on that play. The official announced a holding penalty on the Rams and a "dead ball foul" for the Bengals head shot. He then announced they off set. If the head shot was dead ball shouldn't both penalties technically be assessed? 10 yards back and then 15 yards forward?
