The Baltimore Ravens are expected to hire Mike Macdonald as defensive coordinator.

Macdonald previously worked for the Ravens before becoming defensive coordinator at Michigan. Macdonald's hire at Michigan proved to be one of the most impactful in all of college football last season. 

The Ravens fired Don "Wink" Martindale on Friday after the sides were unable to agree on a contract extension through 2023. In 2018, Macdonald interviewed for the Ravens defensive coordinator position that eventually went to Martindale.
