Two key Michigan offensive linemen could be nearing a return to action.

According to Michigan line coach Ed Warinner, starting tackles Jalen Mayfield and Ryan Hayes are back at practice.

“They’re both practicing, so we’re just working seeing how quickly they can come back,” Warinner told reporters on Wednesday. “They’re both getting out there and doing practice reps, so it’s good to see them out there.”

Warriner held off any guarantees, but seemed optimistic the Wolverines would get their bookends back for this weekend’s game.

“I won’t say anything other than that, but they are not in the training room during practice,” he said. “They are on the field in gear working out and we’re moving them along. They want to get back as quickly as they can, so we’ll see when that is. Both or one might be available Saturday.”

Mayfield and Hayes have been out of action since the second game of the season. The Wolverines have struggled mightily without them, going 1-2 with a triple overtime win over Rutgers in that span.

Michigan hosts winless Penn State this week as both programs search for a little bit of momentum.
