Gophers face offensive line challenges against Michigan after injuries

The Minnesota Gophers enter their Week 5 matchup against Michigan with significant concerns on the offensive line. Starting center Ashton Beers is out for the season, and left guard Jaden Ball will also miss the game. This leaves the Gophers' depth severely tested as they work to fill two crucial positions. Brian Callahan, the team's offensive line coach, will look to fill Ball's spot, while Greg Johnson moves from left guard to center. Minnesota's planned starting lineup now has an unfilled left guard position, and several options are being considered to address the gap.
