According to multiple sources including Joe Reedy with the Cincinnati Enquirer and the Miami Herald's Barry Jackson, the Miami Dolphins are close to signing Bengals defensive backs coach Kevin Coyle as their new defensive coordinator, plugging a hole that was left open with Mike Nolan's departure for the Atlanta Falcons.

Joe Reedy writes:

Bengals secondary coach Kevin Coyle concluded his interview with the Dolphins on Thursday. It is not wrapped up yet, but all indications are Coyle will be Miami’s new defensive coordinator after 11 seasons here as the secondary coach.

Armando Salguero with the Miami Herald writes that...

...Coyle is telling people in the Bengals organization that he doesn't have the Dolphins DC job locked up, but that it is looking for good.

The Cincinnati Bengals did receive some good news on Thursday after the Tampa Bay Buccaneers announced that they signed Greg Schiano, closing the door on Mike Zimmer's opportunity to become a head coach in the NFL this year. That means Zimmer will be back as Cincinnati's defensive coordinator to finish out the three-year deal he signed in 2010.
