One of the to players in Michigan’s secondary may not be up to speed when the Wolverines begin fall camp.

Cornerback Ambry Thomas is “working through a little something right now,” head coach Jim Harbaugh said at B1G Media Days last week. Harbaugh, often reluctant to specify injuries, didn’t go into detail or provide a status update.

Heading into the season, Thomas is expected to be a starter.

“Hopeful,” Harbaugh said of Thomas’ status. “Don’t know yet. We’ll see. There’s some things we’re hoping. Hoping for the best — and that would be that he would be there at the beginning of camp, or soon after camp starts.”

Thomas played in all 13 games for the Wolverines last year, spending time in the secondary and as a kickoff return specialist. He totaled nine tackles, broke up a pass and registered one interception on defense and accounted for 412 yards and a touchdown as a return specialist.

With the Wolverines losing so many key pieces defensively from last season, Thomas was expected to make a big leap entering his junior season.
