Ohio State football projected depth chart for the Illinois game Saturday

After starting the season 5-0, including last week’s dominating win over Minnesota, Ohio State hits the road for the second time this season inside the Big Ten to take on a ranked Illinois team that is going to unload everything it can to pull off the huge upset inside Memorial Stadium Saturday.

Football is one of the most physical sports out there, and because of the risk of injury and the development and emergence of players during the season, a team’s depth chart can change on a weekly basis. That’s why, here at Buckeyes Wire, we like to project the depth chart for OSU ahead of each matchup and are going to do our best to figure it out ahead of kickoff in Champaign.

Here’s a look at the projected and predicted two-deep depth chart for Ohio State on both sides of the ball against Illinois.

Quarterback

Ohio State Buckeyes quarterback Julian Sayin (10) takes a snap during the first half of the NCAA football game against the Minnesota Golden Gophers at Ohio Stadium in Columbus on Oct. 4, 2025.

Starter | Julian Sayin

Backup | Lincoln Kienholz

Sayin has continued to look better and better. He leads the nation in completion percentage, and the coaching staff continues to allow him to do more and more through the air. We may see Lincoln Kienholz in some short-yardage and goal-to-go situations.

Running Back

Ohio State Buckeyes running back Bo Jackson (25) runs during the first half of the NCAA football game at Husky Stadium in Seattle on Sept. 27, 2025.

Starter | Bo Jackson

Backup | CJ Donaldson

This depth chart has changed drastically since the opening game against Texas. With the emergence of Bo Jackson, he now seems like the clear starter, and CJ Donaldson seems to be more trusted at this point than James Peoples.

Wide Receiver (X)

Ohio State Buckeyes wide receiver Carnell Tate (17) celebrates a touchdown by wide receiver Jeremiah Smith (4) during the first half of the NCAA football game against the Minnesota Golden Gophers at Ohio Stadium in Columbus on Oct. 4, 2025.

Starter | Jeremiah Smith

Backup | Bryson Rodgers

Wide Receiver (Z)

Starter | Carnell Tate

Backup | Mylan Graham

Wide Receiver (Slot)

Starter | Brandon Inniss

Backup | Quincy Porter

This rotation seems pretty set and looks the same as when we saw Ohio State open the season. All are talented and all will be productive given the chance.

Tight End

Ohio State Buckeyes tight end Max Klare (86) makes a catch during the first half of the NCAA football game against the Grambling State Tigers at Ohio Stadium on Sept. 6, 2025.

Starter | Max Klare

Backup | Will Kacmarek

Klare seems to be emerging as a bigger threat in the passing game, while Kacmarek’s blocking is one of the best in the country. This unit is deep, but these two have a clear separation.

Starter | Carson Hinzman

Backup | Joshua Padilla

Left Guard

Starter | Luke Montgomery

Backup | Jake Cook

Right Guard

Starter | Tegra Tshabola

Backup | Gabe VanSickle

Left Tackle

Starter | Austin Siereveld

Backup | Ethan Onianwa

Right Tackle

Starter | Phillip Daniels

Backup | Ian Moore

This unit has been fantastic and deep, but it does appear as though the starting five is the starting five, with the backups pretty well defined as well. It’s good to be able to rotate guys in if needed and not have much of a drop off.

Defensive End

Starter | Kenyatta Jackson Jr.

Backup | Beaux Atkinson

Defensive End

Starter | Caden Curry

Backup | C.J. Hicks

Defensive Tackle (3-technique)

Ohio State Buckeyes defensive end Eddrick Houston (96) works out during spring football practice at the Woody Hayes Athletic Center on March 17, 2025.

Starter | Eddrick Houston

Backup | Tywone Malone Jr.

Defensive Tackle (Nose)

Starter | Kayden McDonald

Backup | Will Smith Jr.

McDonald and Houston are real difference makers, though Houston does seem to be struggling on and off with a lower-limb injury. Smith and Malone add quality depth and keep things fresh, rotating in.

Linebacker (Mike)

Ohio State Buckeyes linebacker Arvell Reese (8) leaves the field following the NCAA football game against the Ohio Bobcats at Ohio Stadium on Sept. 13, 2025. Ohio State won 37-9.

Starter | Sonny Styles

Backup | Payton Pierce

Linebacker (Will)

Starter | Arvell Reese

Backup | Riley Pettijohn

Is this the best linebacking corps in the game? It’s hard to argue against Styles and Reese being the best tandem in the game. Their ability to diagnose and run to the ball allows defensive coordinator Matt Patricia to do a lot up front and in the back end.

Cornerback

Ohio State Buckeyes cornerback Davison Igbinosun (1) celebrates during the first half of the NCAA football game against the Minnesota Golden Gophers at Ohio Stadium in Columbus on Oct. 4, 2025.

Starter | Davison Igbinosun

Backup | Aaron Scott Jr.

Cornerback

Starter | Jermaine Matthews Jr.

Backup | Devin Sanchez

Nickelback

Starter | Lorenzo Styles Jr.

Backup | Bryce West

Safety (Free)

Ohio State Buckeyes safety Caleb Downs (2) warms up prior to the NCAA football game against the Washington Huskies at Husky Stadium in Seattle on Sept. 27, 2025.

Starter | Caleb Downs

Backup | Leroy Roker III

Safety (Strong)

Starter | Jaylen McClain

Backup | Malik Hartford

This is one of the best secondaries in the country, and what we saw in fall camp pretty much continued into the season. The biggest change has been McClain cementing himself as the top option at strong safety.

Kicker

Starter | Joe McGuire

Backup | Nick McLarty

No surprises here. We knew this would be the case heading into the season, and there hasn’t been any reason to change things up.
