Northwestern running back Adonis Smith was helped off of the field Saturday after injuring his leg. Smith had an increased role, with 17 carries, in the Wildcat run game as starter Mike Trumpy (concussion) was not cleared to play.
Kain Colter or Dan Persa will continue to lead the Northwestern rushing attach, but a healthy running back group would help balance the attack. Treyvon Green and Jacob Schmidt will likely see more work if Trumpy and Smith are held out of action this week against Army.
