Michigan and former offensive coordinator Tim Drevno have parted ways, a source confirmed to ESPN.com on Friday.
Drevno, a longtime assistant of Michigan head coach Jim Harbaugh, had been the Wolverines' offensive coordinator and offensive line coach for the last three seasons. His departure was first reported by The Wolverine Lounge.
It was a mutual decision, a source told ESPN's Tom VanHaaren.
Michigan's offensive coaching staff has had several changes since the end of a 2017 season in which the Wolverines finished 91st nationally in points per game. Offensive line assistant coach Greg Frey left for a job at Florida State.
