Athletic director Chris Massaro issued a statement before a news conference Friday. Dasher led the Blue Raiders to a 10-3 record last season and set a bowl rushing record with 201 yards in their 42-32 victory against Southern Mississippi in the New Orleans Bowl.

The Blue Raiders open the season Sept. 2 with a home game against Minnesota.
