Oklahoma's defensive line had been pretty solid this season, even as it was pieced together early with Casey Walker's and Stacy McGee's absences.
Walker has been back for several weeks after missing the first three games due to personal seasons.
Saturday, McGee returned after a six-game suspension for an undisclosed violation of team rules.
McGee didn't start but came on for the final play of the first quarter and saw spot action during the rest of the game, as the Sooners fell to Notre Dame, 30-13.
He finished with one tackle.
BEYER VISITS NORMAN
One of the large group of recruits that Oklahoma hosted for Saturday's game won't ever have a chance to play for the Sooners.
San Antonio Reagan offensive tackle Matt Beyer committed to the Sooners in July.
In early September, though, Beyer had to give up football after a spine condition was discovered following a back injury he suffered last season.
Beyer, who reportedly will not be offered a scholarship, took an unofficial visit for the game.
Last season, the Sooners kept Laith Harlow on scholarship with a medical hardship though he was not able to continue his football career.
HURST MAKES QUICK RETURN
When Demontre Hurst went sliding off the field near a television crane midway through the second, it didn't look good.
Hurst remained on the ground for several minutes as teammates, coaches and trainers crowded around him.
But Hurst eventually made it up and walked off the field under his own power.
