Michigan’s ability to run the football this weekend in the B1G opener against Nebraska is a huge question mark. Not because the Wolverines have struggled on the ground, but because of the status of their top running backs.

Karan Higdon and Chris Evans are listed as day-to-day heading into Saturday’s matchup against the Huskers, set for 12 p.m. ET on FS1. Higdon didn’t play at all in Michigan’s 45-20 win over SMU last week.

“Both have been (banged up),” Harbaugh said in his weekly press conference Monday. “Chris is working through something new now. Karan had been working through something. No real status to give.”

Higdon is currently the team’s leading rusher, even after missing last Saturday. He’s toted the ball 34 times for 228 yards and a pair touchdowns. Evans has registered 172 yards and two touchdowns on 30 carries through three games.

Tru Wilson flashed some potential on Saturday, totaling 53 yards and a touchdown on 11 carries. He would be the Wolverines’ No. 1 option without Higdon and Evans in the mix.

Still, Michigan could have some trouble running the football against Nebraska if neither Higdon or Evans is available.
