The Dolphins have promoted linebackers coach Matt Burke to defensive coordinator, replacing Vance Joseph, who was named Denver's head coach Wednesday.
Burke, who played safety at Dartmouth, has coached in the NFL with Tennessee (2006-08), Detroit (2009-13) and Cincinnati (2014-15).
With the Dolphins this past season he presided over a patchwork linebackers unit that dealt with a bevy of injuries. About the only mainstay was middle linebacker Kiko Alonso, who ended with 115 tackles.
Starters Koa Misi (neck) and Jelani Jenkins (knee, hand) ended up missing numerous games. Misi only played three games while Jenkins missed four of the last five regular season games.
Burke helped plug those holes with linebacker such as Donald Butler, Spencer Paysinger and Neville Hewitt while sprinkling in occasional play from Mike Hull, the second-year undrafted player from Penn State.
This will be Burke's first time serving as a defensive coordinator in the NFL.
