The NCAA is investigating Michigan for allegations of sign stealing, the Big Ten announced Thursday.

The conference said it had informed Michigan State, the Wolverines’ opponent this week, and other future opponents of the probe, adding that it “considers the integrity of competition to be of utmost importance and will continue to monitor the investigation.”

Michigan is accused of using unnamed individuals to attend games of scheduled opponents and other potential College Football Playoff contenders to steal the signs used to relay play calls to both offensive and defensive units, sources told Yahoo Sports’ Ross Dellenger and Dan Wetzel.


Two of its opponents this season told Yahoo Sports that they knew Michigan had their play signs.

“The university is fully cooperating with the Big Ten and NCAA. The investigation is ongoing and will not impact Saturday’s game,” Michigan said in a statement, according to Zack Shaw of 247Sports. “At the University of Michigan, we are committed to the highest ethical and integrity standards for all members of our community.”

Although in-person scouting of opponents was banned in 1994, sign stealing isn’t prohibited.

The Wolverines sit at No. 2 in the AP Top 25 after starting the season 7-0.

Michigan has already drawn the NCAA’s ire this season for Level II recruiting violations.

The school imposed a three-game suspension on head coach Jim Harbaugh for the alleged breaches – which included Harbaugh meeting with recruits during the COVID-19 dead period – after the NCAA’s Committee on Infractions rejected the school’s proposed four-game suspension earlier in August.
