This news was first reported by The Detroit News, and a source familiar with the investigation confirmed the violation.

The NCAA sent a formal notice of allegations to Michigan's athletic department this week, according to spokesman Kurt Svoboda. The university now has 90 days to respond to the charges, which were initially outlined in a draft notice of allegations sent in January.

The draft notice initially included four Level II charges, which involved impermissible contact with recruits and analysts performing coaching duties. Additionally, a Level I charge was lodged against Harbaugh for allegedly failing to cooperate with the investigation. While some of the charges were resolved through negotiations, the Level I charge against Harbaugh could not be resolved by Michigan and the NCAA.

As a result, Michigan imposed a three-game suspension on Harbaugh to start the upcoming season. The NCAA Committee on Infractions rejected a proposed four-game suspension as part of a negotiated resolution. It is important to note that the current notice of allegations is separate from the ongoing NCAA investigation into in-person scouting and sign stealing.

Harbaugh had previously been suspended for three games by the Big Ten for violations of the league's sportsmanship policy related to an alleged in-person scouting ring coordinated by former staffer Connor Stalions.

The formal notice of allegations now paves the way for an infractions hearing, which is expected to take place sometime in 2024. When the hearing occurs, potential outcomes may include a show-cause penalty for Harbaugh and an additional suspension during the 2024 season.

Michigan and Harbaugh are now faced with the task of mounting a defense against the Level I violation charge, ensuring a thorough response is delivered within the 90-day window. The university's athletic department will likely work closely with legal counsel to strategize their defense.

This latest development will undoubtedly have an impact on the Michigan football program and raises questions about the potential consequences for Harbaugh, who has been at the helm of the Wolverines since 2015. As the proceedings unfold, the college football world will be closely watching for updates on the case and its potential implications for Jim Harbaugh and the Michigan program.
