Nov. 20--Illinois freshman running back Ke'Shawn Vaughn is considered "doubtful" for Saturday's game at Minnesota, according to the team's injury report released on Thursday.
Vaughn left last weekend's loss to Ohio State with concussion symptoms.
He earned significant playing time while top running back Josh Ferguson missed three games earlier in the season with a shoulder injury and leads the Illini with 661 yards and six touchdowns on 145 carries.
Reserve running back Henry Enyenihi (knee) is listed as probable.
