College football fans took a collective gasp during Cincinnati’s game against Memphis on Thursday after Bearcats quarterback Gunner Kiel suffered a vicious blow to the head late in the first quarter.

Kiel was motionless for several minutes while trainers rushed to help. Facing a 3rd-and-1 near midfield, Kiel picked up the first down on a keeper and during the process of sliding to the turf, was hit in the head by a Memphis defender’s shoulder.

The play was originally ruled targeting, but was overturned.

Kiel did not return to the game and was rushed to a local hospital. ESPN later revealed the quarterback was not believed to be paralyzed and had movement in his arms and legs.

Kiel left last week’s game against Miami (Ohio) with a head injury, but cleared concussion protocol prior to Thursday’s contest against Memphis.

This story will be updated when more details are released.
