Big Ten suspends Michigan football coach Jim Harbaugh for the last three regular-season games.
Allegations involve a sign-stealing scheme by analyst Connor Stalions, violating NCAA rules.
Big Ten Commissioner Tony Petitti's quick decision comes 23 days after the NCAA's initial notification.
The Big Ten cites a violation of the Sportsmanship Policy due to an extensive scouting scheme.
The scheme aimed to gain an unfair advantage by stealing opponents' signs, compromising competition integrity.
Harbaugh denies knowledge of the scheme and maintains he never instructed staff to break NCAA rules.
Detailed evidence includes a master spreadsheet, ticket purchases, and photos/videos of scouting activities.
While the NCAA is still investigating, the Big Ten took immediate action to enforce its sportsmanship policy.
Michigan's president, Santa Ono, seeks a court order to overturn Harbaugh's suspension, citing due process concerns.
Harbaugh's suspension only applies to the regular season, not affecting potential postseason games.
