Late in the first quarter of Baylor's 41-12 win over Oklahoma on Thursday night, Sooners wide receiver Sterling Shepard was knocked out of the game on a hit by Baylor cornerback K.J. Morton.
Shepard appeared to catch the pass from Blake Bell before Morton's hit.
The pass was ruled incomplete.
Shepard stayed on the ground for several minutes and a cart was brought onto the field before Shepard was able to walk off the field with assistance. He did not return.
The sophomore has had head injuries in the past, suffering a pair of concussions during his sophomore season at Heritage Hall. Shepard missed two games after his second concussion.
Morton was flagged for targeting and Baylor was called for two unsportsmanlike conduct penalties on the play.
Morton's targeting ejection was overturned after review showed that it was Morton's shoulder that made contact with Shepard's head.
Shepard wasn't the only injured Sooner.
Jordan Evans, Keith Ford, Aaron Colvin and Julian Wilson all left with injuries as well.
“It's not good,” Sooners coach Bob Stoops said. “We'll find out. All the guys that went off the field were hurt. We'll see how that ends up.”
The Sooners certainly felt the loss of Trey Millard, who tore an anterior cruciate ligament in his knee against Texas Tech and was lost for the season.
Millard joined the rest of the captains for the pregame coin toss but during the game, the Sooners had plenty of spots when Millard could've made a difference.
“Some things you can't do without 33 out there,” Sooners center Gabe Ikard said. “I don't know if he would've made that big, 20-whatever point difference but we obviously missed him on special teams and on offense, but that's no excuse for how bad we got beat tonight.”
