ANN ARBOR -- Changes continue for the Michigan football coaching staff.
And this one might b the biggest domino to fall yet.
Offensive coordinator and offensive line coach Tim Drevno, a long-time confidant and coach alongside Jim Harbaugh, has reportedly resigned from his position at Michigan.
Sports Illustrated's Bruce Feldman and The Wolverine Lounge first reported the news on Friday, three days after Michigan publicly announced the hire of former Florida head coach Jim McElwain.
Former #OhioState and #Minnesota OLine coach Ed Warinner who was hired as an analyst in Ann Arbor is expected to take over the Wolverines OL with Drevno stepping down.
