The decision comes as a result of an ongoing NCAA investigation into an alleged sign-stealing operation orchestrated by former staffer Connor Stalions. Commissioner Tony Petitti handed down the suspension under the conference's sportsmanship policy, citing a violation of the Big Ten Sportsmanship Policy and compromising the integrity of competition.

Under the suspension, Harbaugh will be prohibited from on-site coaching during Michigan's upcoming matches against Penn State, Maryland, and Ohio State. However, he will still be allowed to attend practices and other team activities.

The University of Michigan is expected to respond to the suspension with legal action against the conference in an attempt to block Harbaugh's suspension. The university claims that the commissioner's action is influenced by pressure from other conference members and lacks impartiality.

The Big Ten defended its decision, stating that it thoroughly reviewed extensive documentation and information during the investigation. The Conference expressed its commitment to fairness and denied any prejudgment or bias against Michigan.

The NCAA, in response to the suspension, clarified that it shared information from its ongoing investigation with the conference to ensure competition integrity. The NCAA emphasized its dedication to addressing time-sensitive issues related to competitive integrity.

Michigan President Santa Ono had previously urged Commissioner Petitti to allow due process during the NCAA's investigation before taking any action. The university challenged the Big Ten's authority to impose disciplinary measures in a response to the notice of potential disciplinary action earlier this week.

At the center of the NCAA's probe is former staffer Connor Stalions, who allegedly orchestrated a sign-stealing operation by creating a network of staff members and contractors to electronically record opponent's sidelines. While sign-stealing itself is not against NCAA rules, the use of electronic devices and in-person advance scouting violates the regulations.

The NCAA is also investigating Jim Harbaugh's involvement in the alleged sign-stealing efforts. They will determine potential consequences for Harbaugh, even if it is found that he had no prior knowledge of the violations.

This suspension marks the second ban for Harbaugh this season, as Michigan previously self-imposed a three-game suspension related to misleading investigators during an NCAA investigation into illegal recruiting and coaching practices during the COVID-19 dead period. A negotiated settlement with the NCAA was rejected, leaving the possibility of further punishment for Harbaugh in that case.

Despite the ongoing investigation, Michigan has achieved impressive victories over Michigan State and Purdue, outscoring their opponents 90-13. The alleged sign-stealing operation has caused disruptions in opposing teams' use of signals, with some coaches claiming knowledge of a Michigan sign stealer present at their past games.
