Update: Detroit Mumford athletic director Donshell English refutes report that Connor Stalions is the team's fill-in football head coach, and adds head coach William McMichael was "ill" but will be back next week.

Connor Stalions is now reportedly the acting head coach for the Detroit Mumford High School football team.

CBS Sports reported Friday that Stalions, the former Michigan football staffer who is the central figure of the NCAA investigation into the Wolverines' alleged sign-stealing scandal, will serve as Mumford's acting head coach for at least one game because head coach William McMichael suffered a "mild stroke" last Friday and was admitted to the hospital.

According to CBS, Stalions will be the acting head coach Friday for Mumford's Week 2 game against Flint Hamady (7 p.m.) and will fill in for the foreseeable future until McMichael returns. This is McMichael’s first season as a head coach after being an assistant for more than 30 years.

Mumford was thumped 47-6 last week by Thurston.

The Mustangs went 1-8 in each of the past two seasons.

The school hired Stalions as the team's volunteer defensive coordinator ahead of the season.

Stalions is the central figure in the NCAA investigation into Michigan's alleged sign-stealing operation that became public during the 2023 season and resigned his position as an off-field analyst shortly after the news became public. He allegedly bought tickets to dozens of games of Michigan's future opponents and had people film coaching signals for future use — a violation of NCAA bylaws.

The investigation is ongoing, though the NCAA delivered to Michigan a Notice of Allegations relating to the incident in August.

The NCAA also said there's evidence he was indeed disguised in Central Michigan gear with a sideline pass for the Chippewas' 2023 season opener at Spartan Stadium vs. Michigan State.

Stalions, who went to Lake Orion High School and grew up a diehard Wolverines fan, was featured on a Netflix "Untold" show that aired Aug. 27 to share his version of the sign-stealing scandal.
