Michigan has told its biggest boosters that a deal for Jim Harbaugh to become its next head coach is done and that a news conference is scheduled for Tuesday, a source close to Michigan told Adam Schefter.

Interim athletic director Jim Hackett and other officials from the school met with Harbaugh in California Sunday night after he officially parted ways with the San Francisco 49ers.

Details about Harbaugh's contract weren't immediately available but reports earlier this month suggested Michigan offered a six-year contract worth at least $48 million.
