Reports: Dolphins hiring Sean Duggan as defensive coordinator

The Miami Dolphins are hiring Green Bay Packers linebackers coach Sean Duggan as defensive coordinator, according to multiple reports on Sunday.

Duggan, 32, follows his longtime colleague, new Dolphins head coach Jeff Hafley, after they coached together at Ohio State, Boston College and Green Bay.

They were together for both of Hafley's years with the Packers, with Duggan brought in as a defensive assistant in 2024 and promoted to linebackers coach in 2025 under Hafley as defensive coordinator.
