With Duffner set to return the Jaguars defensive staff will again feature Mel Tucker, Joe Cullen and Duffner at the forefront. An earlier tweet from Ganguli also said that Tucker's title with the Jaguars has been changed to assistant head coach.

Tucker had an interview with the Minnesota Vikings for their defensive coordinator position before electing to return to the Jaguars as an assistant under Mike Mularkey. Tucker told the media: "I'm all in. I respect the decision that was made. I'm a low-ego guy. Mike Mularkey is a great choice for the Jaguars."
