The Wildcats have won three straight behind a tough defense, but have been inconsistent on the other side of the ball, leaning on running back Justin Jackson while getting erratic play from freshman quarterback Clayton Thorson.
The winner Saturday will take sole possession of second place in the Big Ten West.
