Todd Hoffner, the Mankato football coach cleared of child pornography charges last fall, was fired Monday by the school where he had worked since 2008.
Connie Howard, an attorney with the Inter Faculty Organization, which represents the faculty at state universities, confirmed the firing by Minnesota State University, Mankato in an e-mail Wednesday but did not elaborate on the reason for the dismissal.
She said the union is challenging the termination and Hoffner's reassignment earlier this year from head football coach to assistant athletic director in charge of facilities.
She said the two issues will be consolidated and argued before an arbitrator this summer.
"We expect Coach Hoffner to prevail," Howard wrote.
Dan Benson, a university spokesman, confirmed Wednesday that Hoffner was removed from the payroll earlier this week.
Benson, citing privacy laws, declined to elaborate on the reasons for the firing, saying only that it was a private, personnel matter.
Neither Hoffner nor his attorney could be reached for comment.
