The Dolphins announced that linebackers coach Matt Burke has been promoted to defensive coordinator. The move was expected after Vance Joseph was hired to be the Broncos’ new head coach.

The Fins hired Burke away from the Bengals roughly one year ago today as a contingency plan in the event that Joseph left. Joseph did not get a head coaching job in the last cycle, but he was quickly scooped up the Broncos this time and the Fins are glad that they had their replacement already queued up.
In other Dolphins news, the team signed a number of players to reserve/futures deals this week.
