What happened: Notre Dame said Saturday that sophomore offensive lineman Owen Strebig will miss Saturday night's game against Michigan State with a concussion. His absence had been reported earlier in the week and was confirmed the morning of kickoff.

Why it matters: The change trims depth up front for Notre Dame heading into a prime-time matchup with Michigan State. Strebig is viewed as a reserve lineman, so the immediate effect is more about depth than a projected overhaul of the starting front.

What to watch: Watch for Notre Dame's final offensive-line rotation as kickoff approaches and for any additional availability updates before game time. The teams are scheduled to kick off at 7:30 p.m. ET.
