Detroit Lions player Saivion Smith left the pitch in an ambulance after injuring his neck in his side's NFL match with the New England Patriots on Sunday.
Smith, 24, was taken to a local hospital to be evaluated - with his dad called down from the stands amid worrying scenes. Medics on the field brought out a stabilising board for the corner back before putting him in the ambulance.
During the first quarter, Smith was trying to cover Patriots tight end Henry Hunter when he hit the ground, despite the contact between the pair appearing minimal. As staff tended to him, teammates and opponents gathered around the player.
