In consecutive days, Michigan has lost two defensive assistants to arch rival Ohio State.

Linebackers coach Al Washington, who completed his first year on Jim Harbaugh’s staff, is heading home to Columbus where he grew up and will join Ryan Day’s staff at Ohio State.

Washington’s father, Al Washington, played for the Buckeyes from 1977-80.

Day has raided Michigan’s defensive staff the last two days, hiring defensive line coach Greg Mattison as a co-defensive coordinator.

Washington and Day coached together at Boston College. Day overlapped one year at Florida with Mattison.

“Al Washington is going to be a terrific addition to our coaching staff,” Day said in a statement. “I’ve known him as player and as a coach and I know his family very well. I think his familiarity with this region as a coach and as a recruiter is going to be very impactful, as will his leadership with our linebackers unit.”

Michigan has lost three assistants from Harbaugh’s 2018 staff, including Jim McElwain, who coached receivers for one season with the Wolverines and is now the Central Michigan head coach.
