Michigan's second spring game of the Jim Harbaugh era is set for April 1.
The Wolverines will hold a free scrimmage on a Friday evening after drawing an estimated 45,000 fans on a Saturday afternoon last spring.
While Harbaugh stresses the importance of competition throughout his program, there won't likely be a lot of jobs open in Ann Arbor this spring.

A big exception, though, is at quarterback. Jake Rudock graduated after earning All-Big Ten honorable mention for the Wolverines as a graduate transfer from Iowa last season.
He threw for 3,017 yards (second most in a single season in school history) and set a school record by completing 64 percent of his passes.
Among the competitors to replace him is fellow Fort Lauderdale (Fla.) St. Thomas Aquinas product John O'Korn, who sat out last season after transferring from Houston.
Also scheduled to return are Shane Morris, who redshirted last season after losing the battle with Rudock for the starting job, along with 2015 backup Wilton Speight and redshirt freshmen Alex Malzone and Zach Gentry (who reportedly spent some time in bowl practices at tight end).
Brandon Peters, a four-star freshman from Indiana, has enrolled early, and fans could also get their first look at five-star freshman running back Kareem Walker and four-star linebacker Devin Bush Jr.
