The Ohio State football program has lost its second assistant coach with news that Justin Frye is headed to the Arizona Cardinals.

Ohio State offensive line coach Justin Frye is leaving for the Arizona Cardinals, a source confirmed Saturday. ESPN first reported Frye, who spent three seasons with the Buckeyes, was expected to also be the Cardinals’ offensive line coach.

His departure leaves the defending national champion Buckeyes with two coaching vacancies after DC Jim Knowles left to go to Penn State.
