IRVING, Texas — The Dallas Cowboys have fired defensive coordinator Brian Stewart after two seasons.

Stewart coached the San Diego Chargers' secondary for three seasons before following coach Wade Phillips to the Cowboys. Stewart also spent two seasons as a defensive assistant with the Houston Texans.

Though Stewart had the title of defensive coordinator with the Cowboys, his actual responsibilities were unclear. Phillips, a former defensive coordinator, sometimes took over play-calling duties and other times left it unclear who was making the defensive decisions.

The Cowboys gave up 22.8 points per game, which was 20th in the league.
