Ohio State’s preparation for USC now includes a quarterback competition, with Luke Fahey and Tavien St. Clair vying to replace injured starter Julian Sayin ahead of Halloween.
The Buckeyes have a bye before their October 31 visit to Los Angeles, giving Ryan Day time to evaluate both quarterbacks after Saturday’s 19–15 victory over Indiana.
A fresh USC Trojans On SI report identified the competition as a central question, with Sayin out indefinitely and no replacement starter confirmed in that account.
That uncertainty changes preparation for both teams. Ohio State must establish how its offense functions with a different quarterback, while USC must account for more than one possible starter.
Fahey’s early experience becomes more significant
Fahey finished the Indiana game after Sayin left with an injury. Ohio State’s game coverage recorded the freshman taking over, making him part of the succession discussion.
The university’s official Fahey biography lists the Mission Viejo, California, native at 206 pounds. He wears number 13 and entered college after a productive high school career.
His senior season included 3,199 passing yards and 25 touchdowns, according to Ohio State. Across his career, he exceeded 7,000 passing yards and threw 68 touchdowns overall.
Those numbers explain part of his appeal, but they cannot resolve the current competition. College protections, defensive disguises and decisions under pressure present different demands from high school production.
Ohio State has already given Fahey opportunities beyond practice. His roster biography records a passing touchdown against Ball State and another against Kent State in limited action this season.
Against Kent State, he completed four of five passes for 141 yards, including a 75-yard completion. That offers a glimpse of potential without establishing how he would handle USC.
St. Clair remains part of the decision
St. Clair gives Day another option during the evaluation period. Ohio State’s roster lists the sophomore from Bellefontaine, Ohio, at 235 pounds, wearing number nine for the Buckeyes.
The physical contrast is clear, but size alone does not determine the choice. The staff must assess command of the offense, execution and decision-making across practice repetitions.
The bye creates room for that work before the team travels west. It also gives Ohio State time to shape its approach around whichever quarterback earns the starting assignment.
Sayin’s absence is the immediate issue, but his recovery timetable remains uncertain. Available reporting does not justify declaring a return date or treating the quarterback decision as settled.
USC has another conference test first
The Trojans cannot devote their attention entirely to Ohio State. USC’s official schedule places a road game at Wisconsin on October 24 before the Buckeyes arrive at the Coliseum.
USC is 6–1 overall and 3–1 in the Big Ten after beating Penn State 31–23. The Trojans have won two straight games.
That sequencing matters for preparation: USC must address Wisconsin while monitoring Ohio State’s quarterback developments. The Buckeyes, meanwhile, can use the open week to focus on the transition.
For Fahey, the potential assignment also carries a California connection, with his hometown in Orange County. That adds interest without changing the standards required to win the job.
The next meaningful development will be Day’s choice and any confirmed update on Sayin. Until then, the quarterback competition remains a major variable in an important Big Ten matchup.
