The Ravens will keep defensive coordinator Rex Ryan and promote him to assistant head coach.

The team will hold a news conference this afternoon at 2 at the team’s Owings Mills complex, with head coach John Harbaugh to announce Ryan’s return.

Ryan was fired along with all of former coach Brian Billick’s assistants Dec. 31. He interviewed to be Billick’s successor and spoke with the Atlanta Falcons and the Miami Dolphins about their vacant head coaching positions.
