When asked about his staff after the Fiesta Bowl loss on Saturday night, Urban Meyer left the door open for changes to be made.

As it turned out, Meyer opened and closed the door emphatically.

Fox Sports’ Bruce Feldman first reported on Tuesday that Ohio State hired NFL assistant Ryan Day to replace Tim Beck as co-offensive coordinator and quarterbacks coach. Ohio State confirmed part of that news and introduced Day just as quarterbacks coach, but not as coordinator.

SBNation first reported that Ohio State will hire former Indiana coach Kevin Wilson to take OSU’s open offensive coordinator position.

Feldman later confirmed that report:

Wilson resigned at Indiana over “philosophical differences” with Indiana athletic director Fred Glass. That was amidst reports of player mistreatment.

The resignation came after Wilson led Indiana to back-to-back bowl berths for the first time in 25 years. Wilson was the mastermind behind the Hoosiers’ best offensive season in school history in 2015.

Before Wilson got to Indiana, he was the offensive coordinator at Oklahoma, where he led the Sooners’ high-powered offensive attack against Florida in the 2009 BCS National Championship. Wilson won the Broyles Award as the nation’s top assistant.

In addition to the nine years he spent at Oklahoma, Wilson was also an assistant at Miami (Ohio) and Northwestern for 12 years.

According to Cleveland.com, current co-offensive coordinator Ed Warinner is expected to stay in the OSU staff, though it’s unknown what his role will be.
