Notre Dame will have all of its starting defensive linemen when the No. 22 Irish (3-1) play host to No. 14 Oklahoma (3-0) on Saturday.
Coach Brian Kelly told reporters Thursday that Sheldon Day, who sat out against Michigan State with a sprained ankle, practiced all week and will play against the Sooners.
"Anytime you're coming back from an injury in the time frame that he has, you got to feel good that he's been able to respond," Kelly said.
Kelly also said he was pleased with how the Irish filled in for Day last week as the Irish held the Spartans to 119 rushing yards and had a sack in last week's 17-13 win.
"We played Jarron (Jones)," Kelly said. "Obviously Kona (Schwenke) played a great deal. We were pleased with his play. Tyler Stockton played. (Isaac) Rochell played. Ishaq played. A lot of those guys got in the rotation and played a lot of reps. I see that happening again more this weekend as well. You're going to continue to see that kind of rotation."
Kelly also said freshman Malik Zaire, who was available for the first time last week after recovering from mononucleosis, remains the team's third-string quarterback and that the time out because of the illness didn't put him behind schedule.
"He's still in that learning curve as a freshman quarterback, seeing, learning," Kelly said. "We kept traveling him even though he wasn't playing. I think he's still in that learning curve. If two guys got injured, he'd be starting for us. He's just the third quarterback."
