Terrifying scene during the early NFL game on Monday night -- Bills cornerback Dane Jackson suffered a neck injury that was so concerning, an ambulance came straight onto the field to transport him to a local hospital.
Jackson was hurt while making a tackle late in the second quarter of Buffalo's blowout win over the Tennessee Titans.
The 25-year-old was accidentally hit by his own teammate in the face -- and his body bent backward awkwardly. He stayed down on the ground for several minutes as trainers and doctors tended to him.
