The Dallas Cowboys hired 34-year-old Christian Parker as their new defensive coordinator to fix a struggling secondary.

The Dallas Cowboys have agreed to hire Christian Parker, 34, as their new defensive coordinator, replacing Matt Eberflus after a struggling 2025 season. Parker, formerly with the Philadelphia Eagles, helped develop All-Pro cornerbacks Quinyon Mitchell and Cooper DeJean and was instrumental in one of the league’s top pass defenses. The move aims to revitalize Dallas’s struggling secondary, which ranked last in passing defense and allowed a franchise-record 511 points. His appointment marks the fourth defensive coordinator change in as many years for the Cowboys.
