Aaron Williams injures neck, leaves field in ambulance

— -- ORCHARD PARK, N.Y. -- Buffalo Bills safety Aaron Williams was immobilized and taken from the field in an ambulance in the third quarter of Sunday's loss to the New England Patriots.

Williams has a neck injury and did not return to the game. Bills coach Rex Ryan announced after the game that Williams was taken to a hospital for "cervical precaution."

Williams' father said in a tweet Sunday that his son has full movement in his extremities.

Bills safety Duke Williams was one of several players around Williams as he was moved to an ambulance and said he did not see his teammate moving.

"They had told me that he had landed on the side of his neck and he was motionless while he was down," Duke Williams said. "We're concerned about him, so hopefully he's all right."

Players had not been given an update on Aaron Williams' status immediately after the game.

"Guys go down all the time, and when you see guys not moving, that's a concern," Duke Williams said. "Now it's not about football anymore. It's about that person's health, and I'm just praying for him and his family, hoping he's all right."

Aaron Williams was injured diving while trying to tackle Julian Edelman at the end of a 22-yard touchdown reception. An ambulance was called to the edge of the field, and play was stopped for more than 15 minutes while Williams was transported off the field.

The entire Bills bench huddled together in a prayer led by team chaplain James Trapp after Williams was moved to the ambulance.

Williams, 25, is in his fifth season with the Bills and his third as their starting safety.
