The Baltimore Ravens have fired Don Martindale as defensive coordinator with one year remaining on his contract.
John Harbaugh issued a statement Friday saying he and Martindale "agreed to move forward in separate directions."
"We have had a great run on defense, and I am very proud of what has been accomplished and the work he has done," Harbaugh said in his statement. "Don has been a major contributor to the success of our defense since 2012, and especially since he became defensive coordinator four years ago. He has done a great job. Now it is time to pursue other opportunities.
"Sometimes the moment comes, and it's the right time. I am personally grateful for our friendship and for everything he has done in Baltimore."
The decision came 12 days after the Ravens' season-ending, 16-13 overtime loss to the Pittsburgh Steelers and came after Martindale had participated in personnel meetings last week.
Baltimore ranked No. 25 on defense last season, the first time the Ravens had finished out of the top 10 in Martindale's four seasons as defensive coordinator.
