LINCOLN -- Work continues for the 21st-ranked Nebraska football team, as they get ready to play at Minnesota Saturday morning. Defensive Coordinator John Papuchis says the Blackshirts will have to work on stopping the Golden Gophers execution. Minnesota uses both sophomore Philip Nelson and freshman Mitch Leidner in their quarterback rotation. Leidner is more of a rushing threat, racking up 344 yards rushing with five touchdowns. Nelson, on the other hand, is more of a pass first quarterback, throwing for 492 yards completing just under 54 percent of his passes. The Cornhuskers will workout again Thursday, ahead of Saturday's 11am kickoff on ESPN.
