Ware suffered a sprained neck and was taken to a local hospital for x-rays as a precaution. Ware was alert and had feeling in all his extremities.
Ware was rushing Chargers quarterback Philip Rivers with 11:28 to play in the fourth quarter when his head smashed into Dombrowski's left hip. Ware's wife, Taniqua, rushed down to the field with several family members.
