Washington and defensive coordinator Jim Haslett have mutually agreed to part ways.
Haslett finished his fifth season with Washington in 2014.
During his time, the Washington defense has finished a collective 29th in total yards and 30th in points per game. This season, the banged-up unit ranked 20th in total yards and 29th in points allowed.
Earlier this month, former Redskins linebacker London Fletcher, speaking on CBS' pregame show, called Haslett "clueless."
"[Haslett] would take the '85 Bears defense and turn them into a mediocre defense," Fletcher said. "He has no idea what he's doing. He's proven year in and year out that he's not a good defensive coordinator."
Fletcher also accused Haslett of potentially "backstabbing" Gruden.
