Cal running back Jaivian Thomas left the field on a stretcher after he appeared to hit his head hard on the field on a first-and-goal run against Oregon on Saturday.

Thomas fumbled the football on the play but the immediate concern from everyone on the field was his health. Thomas stayed down and medical personnel quickly tended to him. Thomas had the facemask removed from his helmet, was immobilized on a stretcher, and then transported to a cart and taken from the field.

Players from both teams surrounded him before he left the field. Thomas appeared to be awake and blinking while Cal players and coaches spoke to him before he left.

Thomas had three carries for 19 yards before exiting the game.

A 5-foot-10 freshman from Oakland, Thomas is in his first season with the Cal football program. Prior to Saturday, he’d appeared in six games while carrying the ball 15 times for 91 yards and a touchdown.
