Cleveland State hired former Illinois athletic director Mike Thomas to fill the role for that school in February 2017.
Less than two years later, Thomas is resigning from his post as Cleveland State's athletic director.
The school announced Tuesday night that Thomas' last day at Cleveland State will be Dec. 31.
Thomas has decided to return to athletics consulting, a position he held prior to joining Cleveland State in 2017, the school said. Cleveland State will appoint an interim athletic director before the holiday break and will conduct a search for a permanent replacement beginning in the new year.
