Kyle Young will be out of Thursday's game at Michigan State with a concussion that he suffered late in Sunday's loss to Michigan, Chris Holtmann said on Wednesday afternoon. The fourth-year head coach did not disclose any estimate for when he'll be back on the court for the Buckeyes.

"It's significant. There's no minimizing it's a significant hit to our depth and our team," Holtmann said. "It happened late in the game. I'm disappointed for him just because you'd like for him to be able to be in every game here late in his career, and certainly one that's against a quality of team that we're playing. I know he's disappointed, but I think he's doing well. He's progressing very well. He's progressing very well in the updates that I've gotten."

Musa Jallow, a fourth-year wing, is a game-time decision while dealing with a sprained ankle, per Holtmann. Ibrahima Diallo, a second-year center who's been out multiple months with a sprained MCL, could continue to be out on Thursday as he continues to get his feet under him. The head coach, though, said it's possible he could be available when asked a followup question about him.

Without Young, Ohio State's frontcourt will be short on depth. Holtmann will rely heavily on E.J. Liddell as a 6-foot-7, 240-pound center, and he'll look to Zed Key and Seth Towns for more minutes than usual at forward.

"We don't have a guy on our roster that plays quite like Kyle and kind of brings his multi-dimension energy and rebounding and physicality. Obviously it's a concern. That's what we've looked at the last couple days. Obviously Seth will be important. Zed, as you mentioned. And then depending if Musa is available, he'll be important as well."
