Nebraska's defensive coaches have kept opponents guessing when it comes to how they use Randy Gregory.

The 6-foot-6, 245-pound Gregory has been a down lineman at left and right end, he's blitzed as a linebacker, he's lined up as a stand-up rush end on the left side, he's dropped into pass coverage.

And he just might do something new Saturday night when the No. 19 Cornhuskers (5-0, 1-0 Big Ten) visit No. 10 Michigan State (3-1).

Gregory is back in top form after he tweaked an old knee injury in the season opener and had minor arthroscopic surgery Aug. 31. The 2013 Big Ten sack champion recorded two against Miami and 2 ½ last week against Illinois.
