John U. Bacon, someone who is in the know at Michigan, is reporting that San Francisco 49ers head coach Jim Harbaugh to the University of Michigan is a done deal.

Matt Barrows of the Sacramento Bee retweeted his post.

We'll find out for sure within 24 to 48 hours of Sunday's game between the 49ers and the Arizona Cardinals. It's been reported that the 49ers and Harbaugh would part ways within that timeframe.

It has been reported that Harbaugh was offered a 6-year, $48 million deal to become Michigan's next head coach.
