Rex Ryan fires Bills defensive line coach Karl Dunbar (Yahoo Sports)

The Buffalo Bills have fired defensive line coach Karl Dunbar in an abrupt move announced by Rex Ryan. In a statement released by the team Sunday night, Ryan called it a difficult decision but added he felt he needed to make a change ''and go in a different direction.'' No other details were provided. Defensive end Mario Williams went public with his complaints about the system and was cut by the Bills earlier this month.
