MIAMI GARDENS, Fl. - The Miami Dolphins and Jeff Hafley have reached an agreement to make the former Boston College head coach and Packers defensive coordinator their coach, per multiple sources.
Hafley replaces Mike McDaniel, who was fired after going 35-33 in four seasons. The Dolphins also fired longtime general manager Chris Grier during the season.
Hafley, who spent two seasons in Green Bay, met with the Dolphins for a second interview earlier Monday before he was offered the job. He will rejoin new GM Jon-Eric Sullivan in Miami.
The 46-year-old Hafley left his job at Boston College in 2024 to become defensive coordinator in Green Bay, where he worked with Sullivan for the past two seasons.
Sullivan, formerly Green Bay’s vice president of player personnel, spent 22 seasons with the Packers before becoming the Dolphins' GM.
Micah Parsons congratulated Hafley on X (formerly Twitter).
