Michigan fired head football coach Sherrone Moore because the university said he violated school policy through an inappropriate relationship with a staff member.
Official reason
The University of Michigan announced that Moore was terminated “for cause” after an internal investigation found what it called credible evidence of an inappropriate relationship with a staff member. Leadership described this as a clear breach of university rules and emphasized that the school has zero tolerance for that kind of conduct.
Other context
Moore was already under scrutiny due to the long-running sign- stealing/advance-scouting scandal, for which he previously received suspensions and NCAA-related penalties while at Michigan. However, reporting is clear that the firing itself is tied specifically to the inappropriate relationship and resulting policy violation, not his on-field record or just the sign-stealing case.
