Michigan has dismissed head coach Sherrone Moore after a university investigation concluded there was “credible evidence” he engaged in an inappropriate relationship with a staff member, athletic director Warde Manuel announced on Dec. 10, 2025. The decision ends Moore’s tenure after a 9-3 2025 season in which Michigan finished 18th in the College Football Playoff rankings.

Background
The move comes after Moore took over Michigan’s program from Jim Harbaugh and posted an 18-8 record overall. Michigan entered the 2025 season with high expectations and finished with a 9-3 mark, enough to place it 18th in the College Football Playoff rankings. University athletic departments typically maintain conduct policies that govern staff and coach interactions with employees; violations can trigger internal reviews and personnel action. In recent years, colleges have increased scrutiny of workplace relationships and conduct as part of broader efforts on accountability and safety.
Sherrone Moore’s hiring had been viewed as a continuity move for Michigan football after the Harbaugh-era transition, and his on-field results this season kept the program competitive nationally. Still, institutions distinguish between performance on the field and adherence to institutional rules; alleged policy breaches often prompt separate human resources or compliance investigations. The university’s statement framed this as a policy matter rather than an athletic or competitive judgment, signaling administrative priorities in personnel conduct. Stakeholders — from players to boosters — will now adjust to an interim leadership structure amid postseason discussions and off-season planning.
Main Event
The university announced on Dec. 10, 2025, that an investigation found credible evidence of an inappropriate relationship between Moore and a staff member. Warde Manuel, Michigan’s athletic director, said the conduct violated university policy and that the program maintains a zero-tolerance stance. The announcement followed an internal inquiry; the university has not published the investigative report or detailed findings publicly. Officials acted swiftly to remove Moore from his role and to install Biff Poggi as interim coach to provide continuity for players and staff.
Administrators emphasized the separation between the investigative finding and any criminal or NCAA issues, noting the university’s authority to discipline employees for policy violations independent of outside agencies. Michigan’s leadership also highlighted efforts to protect privacy for those involved while balancing the public interest in transparency for a major athletics program. The timing — after the season concluded — reduces disruption to bowl preparations but raises questions about recruiting and staff retention. Team leadership and players were notified by the athletic department; the department said it would support the program through the transition.
Biff Poggi, named interim coach, will assume immediate responsibility for day-to-day operations, practice planning, and recruitment contacts during the interim period. The athletic department has not outlined whether Poggi will be considered for the permanent role or how long the interim period might last. Michigan’s coaching transition will also engage search firms, university governance structures, and likely input from boosters and alumni, all of which can extend timelines. The program faces an off-season where staff continuity and messaging to recruits will be critical.
Analysis & Implications
The firing of a head coach for conduct-related reasons has both immediate and longer-term consequences. In the short term, Michigan must manage player morale, retain assistant coaches, and reassure recruits who may view coaching stability as a criterion in their decisions. A 9-3 season and a top-20 CFP ranking provide competitive credibility, but administrative disruption can shift momentum in recruiting cycles and staff contracts.
Institutionally, the university’s quick action underscores a priority on enforcing workplace policies regardless of public profile. For Michigan, a high-profile program with substantial donor engagement, the decision signals to stakeholders that policy compliance is non-negotiable. That stance may reduce reputational risk among peer institutions and regulators but could prompt scrutiny from constituents who weigh competitive success heavily when assessing administrative choices.
Legally and procedurally, personnel dismissals based on internal investigations typically focus on evidence standards established by the institution; they do not necessarily imply criminal culpability. The university’s next steps — including whether to release a fuller account to the community or to pursue additional personnel actions — will shape perceptions of transparency. Nationally, college athletics programs watch such cases closely, since precedence affects how other institutions craft and enforce conduct policies.
Comparison & Data
| Metric | Value |
|---|---|
| 2025 season record | 9-3 (CFP rank: 18) |
| Overall record under Moore | 18-8 |
This table highlights the concrete performance metrics tied to Moore’s tenure: a strong 2025 season and an 18-8 overall record. While on-field results are relevant to program evaluation, the administrative finding that led to Moore’s firing was based on conduct policies rather than competitive outcomes. Comparing on-field metrics to personnel actions illustrates how universities balance athletics success with institutional standards.
Reactions & Quotes
“This conduct constitutes a clear violation of University policy, and U-M maintains zero tolerance for such behavior.”
Warde Manuel, University of Michigan (athletic director)
Investigators reported “credible evidence” of an inappropriate relationship, prompting the personnel decision.
ESPN (sports media)
Both the athletic director’s statement and reporting from national sports media framed the action as the result of an internal review, not as a competitive judgment. Officials have emphasized privacy for those directly involved while asserting administrative obligations. Public reaction from fans, players, and commentators is likely to range from support for the university’s process to concern about timing and program stability.
Unconfirmed
- The identity of the staff member involved has not been disclosed by the university and remains private.
- The university has not detailed the nature, timing, or specific conduct that led investigators to conclude there was a policy violation.
- There is no public confirmation that criminal charges or NCAA investigations will follow; these remain separate potential outcomes and are unconfirmed.
Bottom Line
The University of Michigan’s dismissal of Sherrone Moore on Dec. 10, 2025, was driven by an internal finding of “credible evidence” of an inappropriate relationship with a staff member. While Moore’s on-field record (9-3 this season, 18-8 overall) demonstrated competitive success, the university prioritized policy enforcement and workplace standards in its personnel decision. Biff Poggi’s appointment as interim coach aims to stabilize daily operations and preserve recruiting efforts as Michigan moves through the off-season.
Key open questions — including the full investigative record, the timeline for a permanent coaching decision, and potential further actions — will shape how the program rebounds. For stakeholders, the episode underscores that conduct and compliance remain central to program governance regardless of wins and losses. Observers should watch for additional university disclosures and any impact on recruiting, staff continuity, and donor relations in the coming weeks.
