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.
After missing just one defensive play, Hurst was back on the field.
He finished with seven tackles and a sack.
TE'O GETS MILESTONE
Late in the fourth quarter, Irish linebacker Manti Te'o picked up his 400th career tackle.
He followed it almost immediately with No. 401.
Te'o finished with 11 tackles and an interception, which he picked off diving after a Dan Fox deflection.
The play was reviewed before officials upheld it.
“It was a great play by Dan Fox there,” Te'o said. “I was on the sidelines telling the coaches when they were reviewing it that they didn't need to worry. It bobbled around a little bit, but I had it before it hit the ground.”
Te'o picked up his first sack of the season earlier in the game.
EARLY PENALTIES HURT SOONERS
Special teams have generally been a strength for Oklahoma this season but twice on punts early in the game, Oklahoma was penalized for illegal formation.
Those penalties were two of the Sooners five penalties for 39 yards — not an overwhelming number.
The biggest came late in the first half when Bronson Irwin was flagged for holding on what would've been a Blake Bell touchdown run that would've likely sent the game into halftime tied.
The Fighting Irish were penalized just once for five yards.
IOWA STATE KICKOFF SET
The kickoff for next week's game at Iowa State was set for 11 a.m. and it will be televised on ABC (Cox 8).
The game will be the second morning kickoff for the Sooners this season. Oklahoma also kicked off at 11 a.m. for the Red River Rivalry game at the Cotton Bowl earlier this month.
