Former University of Michigan football coach Sherrone Moore remains in the Washtenaw County Jail Thursday, a day after he was fired from his position. 

Moore was booked into the Washtenaw County Jail, both the jail and the Washtenaw County Sheriff's Office confirmed to CBS News Detroit on Wednesday night. 

Washtenaw County prosecutors confirmed to CBS News Detroit that there is an active investigation and that Moore is not expected to be arraigned on charges on Thursday. Pittsfield Township police and Washtenaw County Jail officials said Thursday that Moore is expected to be arraigned Friday afternoon. 

In an earlier news release, Pittsfield Township police did not name Moore, but said officers had responded to a location in the 3000 block of Ann Arbor Saline Road just after 4 p.m. local time for an alleged assault.

The incident did not appear to be random in nature, police said.

"The suspect was lodged at the Washtenaw County Jail pending review of charges by the Washtenaw County Prosecutor. At this time, the investigation is ongoing," police said in the release. "Given the nature of the allegations, the need to maintain the integrity of the investigation, and its current status at this time, we are prohibited from releasing additional details."

The university announced earlier Wednesday that Moore was fired after a university investigation found "credible evidence" that he had been engaged in an "inappropriate relationship with a staff member."

In a statement, Michigan athletic director Warde Manuel said Moore had been "terminated with cause, effective immediately." 

"This conduct constitutes a clear violation of University policy, and U-M maintains zero tolerance for such behavior," Manuel said. 

Moore served as head coach for the past two seasons, leading the No. 18 Wolverines to a combined 16-8 record and a victory in the ReliaQuest Bowl last year.   

The university has appointed Biff Poggi as the interim coach. Poggi previously served as associate coach from 2021 to 2022 before going on to serve as head coach at Charlotte until November 2024. He returned to the Michigan staff in 2025.

Michigan is now gearing up for the Citrus Bowl against No. 13 Texas on New Year's Eve.
