Ohio State’s backup quarterback is true freshman Luke Fahey, not five-star sophomore Tavien St. Clair, who was widely expected to win the job. Fahey got in ahead of St. Clair in both blowout wins where Ohio State used its backups, and he pushed past St. Clair on the depth chart. St. Clair isn’t injured or leaving, based on everything I could find.
Fans have been asking “What happened to Tavien St. Clair?” Here’s the full story, in plain terms.
Who Is Tavien St. Clair?
| Hometown | Bellefontaine, Ohio |
| Size | 6-4, about 230 pounds |
| Recruiting | Five-star, one of the top players in the 2025 class |
| High school | More than 10,000 passing yards and 100 touchdowns |
| 2025 at Ohio State | Appeared in one game: 0-of-2 passing against Grambling State |
| 2026 at Ohio State | Reported at 5-for-7 for 52 yards, one touchdown and one interception |
St. Clair chose his home-state school over more than 25 offers, including Alabama. He was the first in-state quarterback Ohio State signed since Joe Burrow, and he spent 2025 as the third-string quarterback behind Julian Sayin and Lincoln Kienholz.
Who Is Luke Fahey?
| Hometown | Mission Viejo, California |
| Size | About 5-11, 206 pounds |
| Recruiting | Three-star, among the top few dozen quarterbacks in the 2026 class |
| High school | 3,199 passing yards and 25 touchdowns as a senior |
| Ohio State link | Both parents went to Ohio State |
| 2026 debut | In the opener, he went 5-of-6 for 62 yards and a touchdown, with one interception |
Fahey arrived in January as an early enrollee. His coach, Ryan Day, said he works hard and learns from his mistakes.
How the Battle Unfolded
| Date | What happened |
|---|---|
| Jan. 1 | Lincoln Kienholz, the 2025 backup, enters the transfer portal after the Cotton Bowl loss to Miami |
| Jan. 3 | Kienholz commits to Louisville, where he’s now the starter |
| Jan. 12 | Maryland and UCLA transfer Justyn Martin commits to Ohio State for depth |
| Aug. 15 | Fahey sheds his black stripe, and Day says he’s “putting a lot of pressure” on St. Clair |
| Sept. 5 | Against Ball State (56-3), both play, but Fahey goes in first |
| Sept. 19 | Against Kent State (59-3), Fahey is again the first quarterback off the bench |
Why Fahey Passed Him
There’s no single reason, and it isn’t that St. Clair is bad. SI’s report says the issue is that Fahey has seemed to develop faster and made the most of his limited chances.
- Fall camp: Day praised Fahey’s preparation and said he was pushing St. Clair.
- Playing time: Ohio State used Fahey first in both games where backups played, even though Day usually favors older players when competition is close.
- Small samples: Each quarterback has thrown only a handful of passes, so both sides have limited evidence.
What It Means for Ohio State’s Future
St. Clair was long seen as the next starter after Sayin. Some writers expect Sayin to declare for the NFL after this season, which would open the starting job in 2027. That’s why the backup question is a big one.
It’s still early. St. Clair is a young, talented quarterback with eligibility left, and Fahey is a true freshman. Neither has played meaningful snaps in a close game. There’s also no report that St. Clair plans to transfer, though that’s a question some fans ask when a five-star recruit slips.
Why the Backup Matters This Season
Sayin has been sacked 11 times in six games, and Indiana has 20 sacks this season. If Sayin were hurt, Ohio State would turn to its backup in a top-five game. That’s why the depth chart matters now, not just next year.
My Take
I wouldn’t write off St. Clair. A five-star quarterback who’s a sophomore is on a normal timeline, and a backup role this early doesn’t decide a career. But Fahey earned his spot, and Ohio State’s quarterback future is more open than fans thought in January.
