The Big Ten is aware of the ongoing investigation into Jim Harbaugh’s Michigan program.

That investigation was detailed in a Thursday report from Yahoo! Sports. According to that report, the Wolverines are being investigated by the NCAA for potentially scouting opponents in season.

The report mentioned two of Michigan’s opponents from the 2023 season that have claimed Michigan knew their play signs. Sign stealing itself (without the use of in-game electric equipment) does not violate NCAA rules and is a gray area, but teams have been prohibited from scouting future opponents in person during the same season since 1994.

In response to that report, the B1G revealed the league was notified of the NCAA investigation late Wednesday. Michigan State — Michigan’s Week 8 opponent — and the rest of Michigan’s future opponents have also been notified of the investigation.

Here’s the B1G’s statement:

Late Wednesday afternoon, the Big Ten Conference and University of Michigan were notified by the NCAA that the NCAA was investigating allegations of sign stealing by the University of Michigan football program. The Big Ten Conference has notified Michigan State University and future opponents. The Big Ten Conference considers the integrity of competition to be of utmost importance and will continue to monitor the investigation. The Conference will have no further comment at this time.

This investigation is entirely new and unrelated to a previous investigation related to allegations of multiple Level II violations relating to recruiting, staff involvement in practice and use of Zoom in player workouts.
