Ann Arbor — Defensive lineman Ryan Glasgow endured a shoulder injury against Rutgers, but as of coach Jim Harbaugh’s meeting with the media on Monday, he had no update on the severity.

Harbaugh had said after the game he’s hopeful the injury is a strain and not a tear.

Tailback De’Veon Smith said Monday he suffered a high-ankle sprain against BYU. He did not travel the following week to Maryland for the Big Ten opener. Smith has played since but hobbled off the field at Minnesota. He said a Minnesota player “twisted my ankle at the end of the game,” but he added his availability for Rutgers was never in doubt.

“I had to suck it up and be ready for my team,” Smith said.

He said the injury to his right ankle is not limiting, but he has thigh bruises that can prove challenging.

“When you get thigh bruises, your body is limited to what you can do really,” Smith said.

Personnel update

Running back Ty Isaac and defensive lineman Lawrence Marshall were noticeably missing from the depth chart last week, and Harbaugh explain the absences were “internal matters” and would not divulge details. Both players have returned to the depth chart this week.

As for senior defender Mario Ojemudia, who suffered a season-ending Achilles tendon injury in the Big Ten opener at Maryland, Big Ten Network reporter Lisa Byington recently reported that Michigan was going to look into the possibility of securing a medical redshirt for him.

Asked about that on Monday, Harbaugh did not offer much.

“There’s an appeal process,” Harbaugh said, who was then asked if they’re in the middle of that process. “It’s a process.”

Kickoff time set – sort of

The only game-time left to be set for the Wolverines is their game at Penn State on Nov. 21. The Big Ten said Monday the game will either be at noon or 3:30 p.m., and an official announcement will be made after Saturday’s games. Penn State is marketing the meeting with Michigan as a “White Out” game.
