* Nebraska coach Bill Callahan was publicly reprimanded by the Big 12 Conference on Thursday for making an apparent throat-slashing gesture after an argument with an official during the Cornhuskers' game against Oklahoma.

The disciplinary action came five days after Callahan engaged in a heated exchange with referee Steve Usechek following Kejuan Jones' touchdown in the fourth quarter of the Cornhuskers' 31-24 loss. Callahan argued that holding should have been called on the play.
