No. 2 Ohio State visits USC at the Los Angeles Memorial Coliseum on Saturday at 7:30 p.m. Eastern on NBC. The Buckeyes are 6–1 overall and 4–0 in the Big Ten. USC is 6–2 and 3–2 after a 24–7 loss at Wisconsin.
Reported facts: an expected replacement, not a confirmed lineup
USC’s official scouting report says Julian Sayin is out indefinitely following a throwing-arm injury in Ohio State’s 19–15 win at Indiana on October 17. It identifies Luke Fahey as the expected replacement while noting Tavien St. Clair also took first-team repetitions during the bye. Neither is described here as an announced Saturday starter.
Jayden Maiava is USC’s expected quarterback based on current team materials and usage. Ohio State’s official preview lists Jeremiah Smith with 52 catches, 984 yards and 12 receiving touchdowns through seven games. Those totals identify the receiving role, but they were accumulated with a different quarterback situation.
A complete final game-day availability list was not verified at publication. The quarterback report is the documented change; other absences should not be inferred from silence.
ISR analysis: observe how the offense helps the replacement
The useful question is not whether a reserve can reproduce Sayin’s season average. Watch the protection calls, first-down menu and timing of the first read. A shorter throw can be a deliberate answer to pressure rather than evidence of a restricted offense.
USC must still defend the players around the new quarterback. Help toward Smith can change the box count and create another receiver’s opportunity, but that opportunity only matters if the pass protection allows the play to develop.
At the other end, USC’s response to Wisconsin begins with clean possessions: manageable down-and-distance, ball security and answers when the initial route is taken away. The home setting and Ohio State’s cross-country trip are context, not conclusions.
Factors to watch
- Ohio State’s announced starter and any rotation.
- Protection communication on obvious passing downs.
- USC’s help location around Smith.
- Maiava’s next decision after the first read is covered.
