The looming suspension is tied to an NCAA recruiting investigation into Michigan in which Harbaugh faces a Level I violation, the most serious kind in the NCAA’s purview, for not cooperating with NCAA enforcement. While the suspension and negotiations with the NCAA have not been finalized, the expectation is that Harbaugh would miss the first four games of Michigan’s season. That includes four home contests in which Michigan is the prohibitive favorite — East Carolina, UNLV, Bowling Green and Rutgers.
