The Baltimore Ravens have promoted linebackers coach Greg Mattison to defensive coordinator to replace Rex Ryan, sources said on Sunday.
Also promoted was special assistant Vic Fangio, who will become the assistant head coach/defense and coach linebackers, the sources said.
Mattison had been a longtime college defensive coach -- most recently for the University of Florida -- before he joined Ravens coach John Harbaugh's staff prior to the 2008 season.
An announcement is expected shortly. Ravens officials could not be reached for comment late Sunday night.
