An introductory news conference is set for 2 p.m. today at the Marriott Kingsgate Hotel, sources said.
Dantonio has been OSU's defensive coordinator since Jim Tressel's arrival at the school in 2001.
It is still unknown whether Dantonio will stay on board at OSU through the Fiesta Bowl.
It is also unclear who Tressel may appoint to replace Dantonio. Defensive line coach Jim Heacock is a veteran assistant with former head coaching experience. Linebackers coach Mark Snyder has also had his name mentioned for several jobs, including the defensive coordinator position at South Carolina. There were rumblings that Snyder was waiting to see whether Dantonio was heading to Cincinnati before accepting the USC post.
Sources indicated Tuesday that Snyder has about a "90 percent chance" of being appointed by Tressel as the new defensive coordinator.
Sources told Bucknuts.com Monday that Dantonio had outlasted an unnamed LSU assistant to win the derby to replace fired UC coach Rick Minter. Cincinnati was also believed to increase its offer to Dantonio in the last day or so to entice him to take the job.
UC will play one more season in Conference USA before joining the Big East in 2005.
Dantonio, a Zanesville native and South Carolina graduate, coached at Youngstown State, Kansas and Michigan State before coming to OSU. He has been regarded as one of the nation's top assistants in recent years as his OSU defense have ranked at or near the top of the Big Ten in most categories.
Ironically, OSU's opens next season against Cincinnati in Ohio Stadium on Sept. 4, meaning Dantonio would be making his head coaching debut against Tressel and the Buckeyes at the Horseshoe.
