Jim Harbaugh’s initial fears were confirmed.

The Michigan coach thought on Saturday that senior cornerback Jeremy Clark would be out for the season with a torn anterior cruciate ligament. Clark was carted off the field in the fourth quarter during Saturday’s game against Penn State.

Harbaugh confirmed the unfortunate news that Clark will miss 2016 with the season-ending knee injury.

Clark is a fifth-year senior who was off to a good start in 2016. In place of injured All-American Jourdan Lewis, Clark had 10 tackles and three pass breakups through the first four games of 2016.

It remains to be seen whether or not Clark will want or get a sixth year of eligibility. The NCAA has a 30-percent threshold for medical redshirts. Michigan would have to play in at least one postseason game for that to be a possibility for Clark. If Clark does choose to apply for a medical redshirt, it’ll have to wait until after the 2016 season wraps up.

The only silver lining is that Lewis returned to action on Saturday against the Lions and appeared healthy. Lewis  was sidelined for the first three games with an undisclosed injury.

The Wolverines will have their first major test of the season when No. 8 Wisconsin comes to Ann Arbor on Saturday.
