Michigan State was missing a pair of starters for its game against Youngstown State as junior center Travis Jackson and senior safety Isaiah Lewis both missed the game Saturday with undisclosed injuries.
The Spartans also were without junior linebacker Taiwan Jones, who left the game early.
MSU will hope to have those players back in time to play against Notre Dame in South Bend on Saturday.
"With Lewis and Taiwan, they will be I guess you'd say probable," coach Mark Dantonio said. "They'll be able to practice this week. We'll see how well they practice relative to what's going on."
Sophomore Jack Allen started in Jackson's place, which he did last year when Jackson was out with a leg and knee injury.
Sophomore R.J. Williamson started for Lewis and had six tackles.
Senior Jairus Jones played the rest of the way against the Penguins when Taiwan Jones left the game.
OL mixing it up against ND
Senior offensive tackle Fou Fonoti was listed as a co-starter at right tackle each of the past three weeks, but now is listed the as the backup.
Dantonio said has a lot to do with the matchup with Notre Dame's big defensive line, as well as Fonoti coming off injury.
"You look at who you play against and ask your self who is going to be better suited to play against these good people," he said. "Jack Conklin is 230 pounds himself. We have some big 300-pounders up there as well. You look at that and the aspect of Fou coming off of injury. (Saturday) was really his first time he played a lot."
Dantonio said he is pleased with starting tackles Jack Conklin and Donavon Clark.
"Conkling played well," he said. "We'll go with that. Donavon Clark also played well. He's a firm guy. You look for things that people do, you try and, I guess, match your guys up with their guys."
Thomas remains out
Last week, Dantonio said they should know soon when sophomore defensive tackle Lawrence Thomas would be back.
Dantonio said Tuesday that Thomas still is out and added that they hope to have him back "after the break" when MSU has a bye week following Notre Dame.
Dantonio also said when Thomas returns, he will primarily play defense.
"When he does come back – and he will be back – he'll come back on the defensive side of the ball," Dantonio said. "The idea is he does know certain aspects of our offense and can play in there a little bit, maybe part time."
Thomas played fullback for MSU last season.
MSU was without junior defensive tackle James Kittredge early in the season as he recovered from a hernia surgery.
He played against Youngstown State and Dantonio said Tuesday that Kittredge will play more soon.
"He is going to get back in there a little bit more this week more full time," Dantonio said.
