Ohio State is heading into its matchup with Indiana needing a cleaner, tougher night from the offensive line - and it may have to get there without Austin Siereveld.
Ryan Day did not directly say whether Siereveld would be available when he met with reporters Tuesday, but he did lay out a week-opening plan that has Gabe VanSickle back at right guard and Phillip Daniels at right tackle.
“We'll move (VanSickle) back down to guard and move Phil to right tackle and see how the week goes,” Day said.
Daniels is expected back after missing Ohio State’s last four games because of an injury he suffered against Texas. That should help stabilize a group that has already been juggling pieces, but Siereveld’s status remains a major question after he was ruled out just hours before last week’s game against Maryland because of a non-football illness.
If Siereveld can’t go against Indiana, Ohio State would still have an experienced interior with Ian Moore at left tackle, Luke Montgomery at left guard and Carson Hinzman at center. The issue is on the right side, where the Buckeyes could be forced into their fourth different starting combination of the season.
That’s a problem because Indiana’s front has been wrecking game plans all season. Through six games, the Hoosiers rank third nationally with 49 tackles for loss and 20 sacks, and they’ve limited opponents to 2.3 yards per carry, good for fourth in the country.
“It is going to be a huge challenge. They do an excellent job up front on defense.
Their defensive line is one of the biggest challenges we'll have all season. So we've got to have a great week of preparation,” Day said.
Ohio State has already felt what happens when Indiana’s defensive line wins the day. In last year’s Big Ten Championship Game, the Buckeyes lost 13-10 as Julian Sayin was sacked five times and Ohio State managed just 58 rushing yards on 26 carries.
The Buckeyes came into this season with four of last year’s five starters back up front - Montgomery, Hinzman, Siereveld and Daniels - but the first half of the season has still been uneven. Ohio State is tied for 78th among 138 FBS teams with 11 sacks allowed and sits 81st in rushing yards per attempt at 4.3, a drop from last season’s mark.
Indiana’s defensive line has not slowed down. Stephen Daley, who had six tackles for loss and five sacks in 2026, is back along with defensive tackles Mario Landino and Tyrique Tucker, both returning starters from a year ago.
Kansas State transfer Tobi Osunsanmi has also been a major factor off the edge, leading the Big Ten with 9.5 tackles for loss. Daley, Osunsanmi and Oregon’s Matayo Uiagalelei are tied for the conference lead with five sacks each.
“Their defensive line is one of the biggest challenges we'll have all season.”
Ohio State has not yet been beaten up front the way it was by Indiana and Miami in last year’s postseason, but the warning signs are there. The Buckeyes have given up six sacks over their last two games, and Pro Football Focus has them 63rd nationally in pass-blocking efficiency with five sacks and 38 total quarterback pressures allowed on 212 passing plays.
Daniels being out for the last four weeks and Siereveld missing last week both played a part in that. There was some obvious friction in the lineup with VanSickle moving to right tackle on short notice and Jake Cook making his first career start at right guard.
Still, the assignment this week is clear. Ohio State needs its best line performance of the season against a defense that has already proven it can take control in the trenches.
“This is not something that you don't plan for. We have a plan in place.
That's why we recruit depth. That's why we develop depth.
And that's why we have to play depth. And so that's what we're going to have to do in this game, and then be prepared for whatever comes with it,” Day said.
“But the good news is some of these guys have played against Indiana before, so they know how good these guys are and what comes with it. So they're going to have all of our attention for sure.”

Marvin Harrison Jr And C.J. Stroud Just Revived A Buckeye Storyline
Marvin Harrison Jr. is heading from Arizona to Houston, and the move puts him back alongside the quarterback who helped make him one of the most electric receivers in college football. For Ohio State fans, it is a reminder of how quickly Harrisons Buckeye rsum came together, from big nights in the 2022 Rose Bowl and the 2023 Sugar Bowl to the kind of complete performance he delivered against Penn State in 2022.
The trade also gives Harrison a fresh chance after a difficult NFL start, and it arrives with a familiar face at quarterback in C.J. Stroud. For a former Buckeye star trying to reset his momentum, the reunion brings back the kind of setting where his talent looked at its most natural, and it leaves one obvious question hanging over the next chapter of his career.

Ohio State Still Has One Problem Fans Cant Ignore
Ohio States special teams issues have become hard to brush aside, especially when games tighten and every point starts to matter more. The Buckeyes have already lived through missed opportunities in key moments, including a costly field goal miss in the previous Big Ten Championship, and the unit has remained a lingering concern even with Robby Discher brought in to coordinate the operation.
Connor Hawkins entered the season with a track record that suggested steadier days ahead, but his 2026 form has not matched expectations. For a program that usually expects clean execution in the kicking game, the continued uncertainty around field goals keeps showing up in the places Ohio State can least afford it, and until that changes, fans are going to keep watching this part of the team with unease.

Ryan Day Faces One Big Lineup Question Before Ohio State's Indiana Test
Ryan Day sounded encouraged this week about Ohio States health heading into Indiana, saying most of the six starters who missed the Maryland game are expected back. That group included Brandon Inniss, Devin McCuin, Austin Siereveld, Phillip Daniels, Christian Alliegro and Jay Timmons, with some of those absences tied to non-football-related issues. Getting that much experience back would matter for a Buckeyes team trying to keep its rhythm intact as the season tightens.
Indiana, though, gives Ohio State little margin for error. Day pointed to the Hoosiers recent success and made clear they are not the kind of opponent to take lightly, especially with lineup questions still hanging over his own side. The Buckeyes should be closer to full strength, but this matchup still comes with one obvious layer of uncertainty: exactly how quickly those returning starters can settle back in and how much of the rotation changes with them.
