Sherrone Moore jailed as police investigate situation that led to the fired Michigan coach's arrest

ANN ARBOR, Mich. — Sherrone Moore was being held in jail Thursday while police investigate the situation that led to his arrest hours after the once-promising coach was fired at Michigan for what the school said was an inappropriate relationship with a staff member.

Authorities have yet to release details on Moore's arrest, other than to say he has been held since Wednesday night in the Washtenaw County Jail and remains under investigation.

Pittsfield Township police had issued a statement that said officers were called to investigate an alleged assault and took a person into custody, without mentioning anyone by name. The statement, however, was released in response to media inquiries about Moore.

The police department updated its statement in the morning to say the suspect is scheduled for arraignment on Friday.

Moore, 39, was fired by Michigan, college football's winningest program that has been mired in scandal, after the school verified evidence of his relationship with the staffer.

Athletic director Warde Manuel said the behavior ''constitutes a clear violation of university policy.''

The announcement did not include details of the alleged relationship. Moore, who is married with three young daughters, did not return a message from The Associated Press seeking comment.

He led the 18th-ranked Wolverines to a 9-3 record this year after going 8-5 in his debut season.

Moore signed a five-year contract with a base annual salary of $5.5 million last year. According to the terms of his deal, the university will not have to buy out the remaining years of his contract because he was fired for cause.

His firing leaves Michigan suddenly looking for a third coach in four years, shortly after a busy cycle that included Lane Kiffin leaving playoff-bound Mississippi for LSU.

Moore, the team's former offensive coordinator, was promoted to lead the Wolverines after they won the national title. He succeeded Jim Harbaugh, who returned to the NFL to lead the Los Angeles Chargers.

Michigan is set to play No. 14 Texas on Dec. 31 in the Citrus Bowl. Biff Poggi, who filled in for Moore when he was suspended earlier this season in relation to the Harbaugh-era sign-stealing scandal, will serve as interim coach. Moore was suspended for two games as part of self-imposed sanctions for NCAA violations related to the scandal.

Moore previously deleted an entire 52-message text thread with former staffer Connor Stalions, who was at the center of the team's sign-stealing operation. The texts were later recovered and shared with the NCAA.

Just a few years ago, Moore was Harbaugh's top assistant and regarded as a rising star.

Moore, who is from Derby, Kansas, didn't start playing football until his junior year of high school. He played for Butler County Community College in Kansas and as an offensive lineman for coach Bob Stoops at Oklahoma during the 2006 and 2007 seasons.

His coaching career began as a graduate assistant at Louisville before moving on to Central Michigan, where he caught Harbaugh's attention. Harbaugh hired him in 2018 as tight ends coach.

Moore was promoted to offensive line coach and co-offensive coordinator in 2021, when the Wolverines bounced back from a 2-4, pandemic-shortened season and began a three-year run of excellence that culminated in the school's first national title in 26 years.

Moore also served a one-game suspension during that year related to a recruiting infractions NCAA case.

Earlier in the 2023 season, Michigan State fired coach Mel Tucker for cause after he engaged in what he described as consensual phone sex with an activist and rape survivor. In 2012, Arkansas fired coach Bobby Petrino due to a sordid scandal that involved a motorcycle crash, an affair with a woman who worked for him and being untruthful to his bosses.
