According to Inside The Huddle's Michael Spath, the NCAA has denied Jeremy Clark's petition for a sixth year of eligibility:

Clark started seven games at cornerback in 2015 and three in 2016 before tearing his ACL against Penn State. The former three-star safety recruit was a critical component to the last couple secondaries, battling Channing Stribling to a relatively even draw for playing time until the injury.
Without Clark, Michigan will be very inexperienced at cornerback in 2017. Redshirt junior Brandon Watson, who's seen scattered snaps at nickel, is the only upperclassman at the position. Sophomore Lavert Hill and David Long are the favorites to earn starting spots; they'll compete with redshirt sophomore Keith Washington and freshmen Ambry Thomas and Benjamin St-Juste. Unless Michigan picks up another corner in the 2017 class—it looks like they'll get one more—that is the entire group of scholarship corners for next season.
