Allen Park — It was a horrific scene, no matter whether you watched it from the press box seven stories above the field or via the gratuitous number of slow-motion replays shown during the broadcast.
Detroit Lions rookie T.J. Hockenson tried to hurdle a defender, as he's done plenty of times playing football, but it went wrong. Kansas City Chiefs linebacker Damien Wilson hit the airborne Hockenson and sent him spinning. As he landed, the side of his head smashed against the turf and he appeared to lose consciousness.
