FRISCO, Texas -- Mike Nolan has been let go as Dallas Cowboys defensive coordinator, he confirmed to ESPN's Ed Werder on Friday.
Defensive line coach Jim Tomsula was also fired Friday, a source told ESPN.
Last season, the Cowboys (6-10) allowed the most points in franchise history (473) and finished 31st in the league in run defense. In the season-ending loss to the New York Giants, they allowed 23 points, including 20 in the first half, to an offense that had not scored more than 19 in five weeks.
The unit played better down the stretch with 12 takeaways in the final four games after getting just 11 in the first 12 games, but that was aided in part by facing backup quarterbacks in Cincinnati, San Francisco and Philadelphia.
