Colorado’s Deion Smith was taken off the field on a stretcher early in the fourth quarter of Saturday’s game against Cal with an injury.

The junior running back was hit on a first-and-10 play, fumbled, and then stayed down on the field well after the play was over. Trainers tended to him on the field until eventually the entire CU team was out around him. Smith’s mother was also allowed onto the field, where she was met by interim coach Mike Sanford.

It’s unclear what injury Smith may have suffered, but Colorado’s sports information department communicated to the Pac-12 Network broadcast that Smith was getting x-rayed and he was able to move.

Smith had 48 yards on 12 carries before exiting the game. He also had four catches for 17 yards.

CU hosted Cal Saturday after a bye week. Smith entered the game as the team’s leading rusher with 195 yards on 34 carries in five games.
