The lengthy wait for the Miami Dolphins’ defensive coordinator hire is now complete.

The Dolphins are moving forward with Green Bay Packers linebackers coach Sean Duggan for the job, according to a league source Sunday afternoon.

The news came minutes after the Arizona Cardinals decided on Los Angeles Rams offensive coordinator Mike LaFleur to be their next head coach, rounding out the 2026 hiring cycle’s head coaching jobs. The LaFleur hire occurred about an hour after the Las Vegas Raiders chose Seattle Seahawks offensive coordinator Klint Kubiak to lead them.

With the Cardinals opting against hiring former Dolphins defensive coordinator Anthony Weaver, who was a finalist for the job, Miami will not receive compensatory third-round picks in the next two drafts for having a minority assistant leaving for a head role elsewhere.

But it allowed the Dolphins to move forward with Duggan, 32, who has longstanding ties new Dolphins coach Jeff Hafley.

Duggan was most recently linebackers coach last season while Hafley was defensive coordinator with the Packers. He followed him to Green Bay in 2024 as a defensive assistant after being with him at Boston College the four years Hafley was head coach there.

Duggan was linebackers coach at BC from 2020 through 2023, while adding co-defensive coordinator to his title in his last season in Chestnnut Hill.

Also a BC alum, where he played linebacker from 2011 until 2014, Duggan was first with Hafley at Ohio State in 2019, as a graduate assistant.

Hafley, who has a defensive background, said he will call defensive plays for the Dolphins, so Duggan’s role as defensive coordinator will be somewhat limited.

The Duggan news finally surfaced after initial Wisconsin-based reports a week ago that he was leaving the Packers and following Hafley.

In the meantime, the Dolphins have agreed to terms with lower-level defensive assistants, including defensive backs coach Ryan Downard, cornerbacks coach Jahmile Addae and linebackers coach Al Washington. Hafley had also filled in most of his offensive and special teams staff.

Earlier Sunday, the Dolphins agreed to bring on Georgia Tech linebackers coach Darius Eubanks as assistant special teams coach, under special teams coordinator Chris Tabor.
