Teddy Bridgewater was forced to spend Sunday night in a hospital ... after he terrifyingly slammed his head on the grass during the Broncos' game against the Bengals.
The horrifying scene all went down on Sunday in the third quarter of the game at Empower Field in Denver ... when Bridgewater dove for a first down but landed awkwardly on his head and neck.
Video of the play is scary ... you can see in the clip, Teddy appeared to be knocked unconscious as soon as his face hit the turf.
