“Larry’s experience at Ohio State will allow him to have a major role in the guidance and direction of this program,” Day said. “His promotion to associate head coach is well earned. Larry is a wonderful teacher and mentor, and his players always become a part of his family. I am thrilled that he will continue to be a part of this program.”

Additionally, Hafley will oversee the secondary. Specific position responsibilities for Mattison will be announced later.

Hafley has spent the past seven seasons in the NFL, most recently the last three season with the 49ers. Hafley worked with Day during the 2016 season in San Francisco.

Mattison has served 18 seasons as a defensive coordinator or co-defensive coordinator including two with the Baltimore Ravens. He has coached the past eight seasons at Michigan.

“Jeff is a rising star and highly regarded as one of the best secondary coaches in the country. His NFL knowledge coaching the secondary is only going to enhance and improve what has become a marquee area for the Buckeyes. Greg is a terrific coach. His experience as a coordinator and his knowledge of the Big Ten is extremely important to me.

“These are two outstanding coaches and they will provide stability, wisdom and a fundamental approach to everything they teach. They will add to our culture while proving to be excellent coaches and mentors for the young men in our program.”
