Ryan Day has two weeks before Ohio State plays again, and a quarterback decision that could reshape the rest of its season. Julian Sayin is expected to miss several weeks after injuring his throwing arm at Indiana, leaving the Buckeyes to prepare an inexperienced replacement for the October 31 trip to USC.
Freshman Luke Fahey finished Saturday’s 19-15 victory over Indiana, attempting two passes without a completion. That emergency appearance made him the immediate replacement, not a proven answer for the games ahead. Ohio State also has sophomore Tavien St. Clair available, and Day has a bye week in which to weigh how the offense should operate without Sayin.
Day said Sayin would probably be out for “several weeks” but did not disclose a specific diagnosis, Robby Kalland and Austin Nivison reported for CBS Sports. Sayin returned to the sideline with his right arm in a sling after leaving in the fourth quarter. No confirmed return date was supplied.
The win bought Day room in the standings. Ohio State improved to 6-1, secured a road victory over a top-five opponent and ended Indiana’s 22-game winning streak. A defeat would have left the Buckeyes trying to navigate the same injury problem with two losses. Instead, they enter the break with a stronger playoff case and an unsettled offense.
The distinction is important because Saturday’s finish tested survival rather than preparation. Fahey entered a close game on the road against a top-five defense with little time to settle. As The Athletic’s analysis of Day’s quarterback challenge reported, Ohio State gained only 11 total yards on Fahey’s two possessions. Penalties helped prevent either series from becoming a sustained drive.

A planned start would be a different assignment. The staff can choose plays around the replacement quarterback, rehearse the cadence with the offensive line and distribute first-team practice repetitions before traveling to Los Angeles. None of that guarantees a successful debut, but it is preparation Fahey did not have when Sayin went down in Bloomington.
Sayin’s own performance illustrated what Ohio State is losing even on a difficult afternoon. He completed 15 of 29 passes for 235 yards, two touchdowns and two interceptions. His 38-yard scoring pass to Jeremiah Smith on fourth-and-one helped turn a 13-7 deficit into a fourth-quarter lead.
The Buckeyes did not need Sayin to play flawlessly to benefit from his experience. They needed him to identify and execute a decisive throw in a game their offense had struggled to control. Asking a replacement to reproduce that immediately is different from asking him to finish a comfortable win in September.
Fahey’s earlier work provides evidence, but not much of it. CBS reported that he entered the Indiana game having completed nine of 11 passes for 203 yards and two touchdowns across three appearances. Both incompletions had been intercepted. That record combines efficient production with turnovers in a sample too small to establish how he will handle a full competitive game.

That choice also affects the other players. Smith had four catches for 68 yards and a touchdown against Indiana, bringing his season totals to 52 receptions, 984 yards and 12 touchdowns. His production is central to Ohio State’s attack, regardless of whether his Heisman candidacy survives a change at quarterback.
The offensive line has a more immediate responsibility than preserving individual awards. The Athletic reported that veteran lineman Luke Montgomery emphasized taking work off the new quarterback, especially on third downs and with motions. Familiarity with the protection calls and cadence becomes more valuable when the player receiving the snap is learning to direct the first-team offense.
Ohio State is also hoping to recover help elsewhere. The Athletic reported that starting tackle Austin Siereveld and running back Ja’Kobi Jackson could return by the USC game. Those were hopes, not confirmed availability announcements. Their status will help determine how much protection and rushing support Day can build around his quarterback.

The wider college football rankings upheaval gives the Indiana win additional value. Georgia and Notre Dame also lost Saturday, changing the national picture around Ohio State. But a better position in the next poll will not resolve the problem of moving the ball in the next game.
Day’s task is narrower than recreating Sayin’s entire offense in two weeks. He needs to identify which quarterback can manage the available plays, which responsibilities experienced teammates can absorb and which risks the defense can help him avoid. The Indiana result preserved Ohio State’s margin for error. Preparing the replacement will determine how much of that margin remains when the Buckeyes return to the field.
