With Julian Sayin sidelined for several weeks after a right shoulder injury in Ohio State’s 19-15 win at Indiana, true freshman Luke Fahey has the stronger case to start based on how he earned the QB2 role and coach Ryan Day’s comments, though sophomore Tavien St. Clair’s pedigree and the upcoming bye week keep the door open for evaluation.
Sayin, a Heisman contender, exited in the fourth quarter after a sack by Indiana’s Mario Landino and returned to the sideline in a sling. Day said afterward that Sayin will “probably be out for several weeks,” leaving the 6-1 Buckeyes to navigate a bye and then a road game at USC on Oct. 31 (followed by Oregon and Northwestern) without their starter.
Fahey, the 5-foot-11, 206-pound three-star from Mission Viejo, California (No. 586 overall in the 2026 class), entered first after Sayin went down. He went 0-for-2 passing in limited late-game action, with an 8-yard scramble on his first play that drew a personal foul. Earlier in non-conference play he was 9-for-11 for 203 yards, two touchdowns and two interceptions (high yards per attempt), mostly in blowouts of Ball State and Kent State. He has been the first quarterback off the bench all season.
Day has consistently framed the competition around earned trust rather than recruiting ranking.
In August camp he said of Fahey: “He’s really been going a great job. He’s putting a lot of pressure on Tavien. He really is. He’s been competing. He’s been making plays.” He added that Fahey arrived with work ethic and was “run[ning] the offense at a pretty high level.”
After Fahey entered ahead of St. Clair in the Ball State opener, Day noted both played well in a planned split of series but that the staff “decided to put Luke in first” and would continue evaluating.
By mid-September, after Fahey again entered first, Day was clearer: “Every day you walk in this building, you have an opportunity to prove yourself and to earn trust. Luke has done that. He’s been the first one in the game the last couple of games, and if he continues to do what he’s doing, I would continue to see it going that way.” He added that St. Clair “is working hard, so he’s right there, too.”
After the Indiana game Day described Fahey’s insertion as “a tough spot” in which the game was “moving fast,” with the staff trying to “calm him down a little bit.” He highlighted the scramble: “You can see on that scramble that he made. He stepped right up. He’s got confidence. He’s got athletic ability.” Day called him “a competitive kid” for whom “the moment [was] not too big,” just the speed of the game. Looking ahead he said the team would “come together and figure this out,” noting that “when Luke’s in there, we just may need to do things just a little bit differently” and that the bye gives time to regroup.
Teammates have echoed the trust. Offensive lineman Luke Montgomery said Fahey has “a certain moxie” and that the staff wouldn’t have put him out “if we didn’t have trust in him.” Wide receiver Jeremiah Smith told Fahey on the sideline that the offense had his back.
Luke Fahey:
Pros: He has already won the in-season competition for QB2 through practice and early-game performance. His limited sample shows efficiency and big-play ability. Day and teammates have repeatedly cited his confidence, competitiveness, athletic ability and ability to handle pressure. He adapted quickly as a true freshman and is the known commodity the staff has prepared.
Cons: Extremely limited experience, especially against Power conference defenses in meaningful situations. Undersized relative to typical Ohio State quarterback prototypes. The two interceptions and the stalled late drive against Indiana show the learning curve. Any start against USC would be his first.
Tavien St. Clair:
Pros: Elite physical tools and recruiting pedigree (five-star, top-of-class talent from Bellefontaine, Ohio; listed around 6-4, 230-235 pounds). An extra year in the program. Flashed efficiency in limited early-season work (roughly 5-for-7 for 52 yards and a touchdown against Ball State). Higher long-term upside if he can close the gap in practice.
Cons: Has not earned the QB2 role despite the opportunity; a three-star freshman has consistently been preferred. Limited recent snaps and less demonstrated trust from the coaching staff. Inconsistent results in the small sample (including an interception). Development has lagged the expectations that accompanied his arrival after Lincoln Kienholz transferred.
Day’s words and the team’s actions this season point to Fahey as the next man up. He has done the things the staff said mattered—earning trust daily, competing in practice, and performing when given early opportunities—while St. Clair has not separated himself enough to overtake him. The bye week provides time to install and refine a plan around Fahey (or to reassess if St. Clair closes the gap dramatically in practice), but the baseline expectation entering the USC game is Fahey under center.
Ohio State’s roster and defense give it margin, yet the stretch of USC, Oregon and Northwestern is unforgiving. The staff’s repeated emphasis on preparation and earned opportunity suggests they will go with the quarterback who has already proven he can operate the offense at a high level in their building. That has been Fahey.
