Colts tight end Brandon Williams was carted off the field at the start of the second quarter tonight. While the play responsible was not itself anything especially out of the ordinary, Williams has spinal stenosis, which can make any football injury scary and ended his college career when he was declared medically ineligible to play.

He lay on the field, surrounded by medical personnel, for more than 10 minutes before being carefully transferred to the cart and leaving.

He’s being transported to the hospital with a head injury, according to the broadcast.

Update (1:15 a.m. ET 12/15/2017): Williams has been diagnosed with a concussion and released from the hospital, per ESPN.
