LINCOLN, Neb. (AP) - Michigan heads to Minnesota this week with more questions than answers on offense.

The Wolverines have gone two straight games without scoring a touchdown - a first since the early 1960s - and they played the second half of Saturday's 23-9 loss to Nebraska without quarterback Denard Robinson.

Robinson injured a nerve in his right elbow late in the first half. Coach Brady Hoke said after the game he wasn't concerned about Robinson's availability this Saturday.

The Wolverines (5-3, 3-1 Big Ten), who dropped out of the Top 25, share first place in the Legends Division with Nebraska, but the Cornhuskers own the tiebreaker.

Receiver Roy Roundtree said he's at a loss to explain why the Wolverines have struggled to find the end zone.
