Michigan football is dealing with a second NCAA investigation, according to a new report.

Ross Dellenger and Dan Wetzel of Yahoo Sports report, per sources, that the NCAA is looking into alleged violations of rules that prohibit teams from scouting future opponents in person. The Yahoo report notes that NCAA Bylaw 11.6.1 reads: “Off-campus, in-person scouring of future opponents (in the same season) is prohibited.”

The NCAA is looking into whether Michigan is sending people to attend games of future scheduled opponents, as well as potential postseason matchups, to gather signs. Sign stealing is not technically prohibited by the NCAA, but in-person scouting of opponents has not been allowed since 1994.

Yahoo’s report does not cite specific teams that U-M staffers have observed in person. It notes that Big Ten conference officials and the Michigan State football team have each been notified of the NCAA probe.

The new investigation is not related to Michigan’s other NCAA case. The program has been accused of multiple Level II violations relating to recruiting, staff involvement in practice and use of Zoom in player workouts. Wolverine head coach Jim Harbaugh served a 3-game self-imposed suspension to open the 2023 season in relation to that NCAA case.

No. 2 Michigan faces Michigan State in Week 8. Saturday’s rivalry clash is set for 7:30 p.m. ET on NBC.
