PHOTO: Indiana celebrates 'former basketball manager' Jim Harbaugh's birthday

Michigan's Jim Harbaugh celebrates his 52nd birthday Wednesday, and the greetings are coming in from across the Big Ten - even across sports.

The first-year Wolverines coach is the brother-in-law of Indiana basketball coach Tom Crean, and back in 2012 while coaching the San Francisco 49ers, Harbaugh served as a manager for a Hoosiers game, carrying chairs for timeouts.

Indiana sent him some birthday greetings, complete with a photo of Harbaugh in action during his managerial stint.

Of course, the Ohio native was rocking his trademark khaki pants in the photo.
