Razorbacks coach Bobby Petrino announced the move Sunday and said Johnson would be an assistant head coach.

Johnson spent five seasons with Ohio State, which compiled a 50-15 record during his tenure and won four Big Ten titles. Ohio State finished with a 12-1 record in 2010 and a victory in the Sugar Bowl.

Johnson briefly served as the defensive line coach with the Oakland Raiders after five years at Miami (Ohio), and he spent a year with the Cleveland Browns as special teams coach.
