Mike Mularkey has his coordinators in Jacksonville.

ESPN's Adam Schefter reported Thursday night that Mel Tucker, the Jaguars' interim head coach, turned down an opportunity to be the Vikings' defensive coordinator to remain in Jacksonville.

The Jaguars confirmed the move on Friday. "I'm all in. I respect the decision that was made," Tucker said. "Mike Mularkey is a great choice for the Jaguars."

Joining Tucker in remaining with the Jaguars' staff is defensive line coach Joe Cullen. "It's exciting to be back and continue to work with the (defensive line) room Gene Smith has put together," he said.

Joining Tucker and Mularkey will reportedly be Falcons QB coach Bob Bratkowski, per Schefter. Bratkowski, who was the Bengals' offensive coordinator for 10 seasons, joined the Falcons' staff last season as the quarterbacks coach, where Mularkey was offensive coordinator. Bratkowski was Seattle's offensive coordinator from 1995-1998.

Tucker was 2-3 as an interim head coach. He helped the Jaguars' defense improve from being ranked 28th in the league in 2010 to sixth in 2011.
