Mike Zimmer will not return as the Dallas Cowboys defensive coordinator in 2025, he tells Ed Werder. He’s expected to retire from coaching and the NFL, per the report, and the Cowboys are ‘likely’ to hire former Chicago Bears head coach Matt Eberflus to replace him.

Matt Eberflus has a new job. The Cowboys hired the ex-Bears head coach to be their defensive coordinator on Tuesday, according to NFL Network’s Tom Pelissero . Eberflus spent parts of three seasons in Chicago, going 14-32, before being fired in late November after a 4-8 start to the 2024 campaign.

The Chicago Bears have officially entered a new era after hiring Ben Johnson as their next head coach for the 2025 NFL season, but their previously dismissed leader — Matt Eberflus — has already landed on his feet again.
