Texas starting quarterback Quinn Ewers suffered an apparent left shoulder injury in the first quarter of the Longhorns' 20-19 loss to No. 1 Alabama on Saturday and did not return.
Ewers was taken to the locker room for an X-ray, a source told ESPN's Pete Thamel, after the freshman quarterback was driven into the ground by the Crimson Tide's Dallas Turner late in the first quarter.
Ewers was wearing street clothes when he returned to the sideline in the second half.
Turner was flagged for roughing the passer after landing on Ewers on the first-quarter play, with the official saying it was because he drove Ewers into the turf.
