Brian Callahan has been fired as head coach of the Tennessee Titans after a 1-5 start in the 2025 NFL season. The Titans have not yet announced a permanent replacement. In the meantime, veteran coach Mike McCoy has been named the interim head coach to lead the team for the remainder of the season, but he is not expected to be the long-term solution.

As for candidates to replace Callahan permanently, several names are being considered and discussed in the NFL coaching market:

• Kliff Kingsbury, Offensive Coordinator of the Washington Commanders, known for his offensive schemes and quarterback development.
• Joe Brady, Offensive Coordinator of the Buffalo Bills, recognized for his creative and quarterback-friendly offensive strategies.
• Matt Nagy, former NFL head coach with experience developing quarterbacks.
• Mike Kafka, Offensive Coordinator of the New York Giants, noted for his work with quarterbacks.
• Mike McCarthy, former head coach of the Green Bay Packers and Dallas Cowboys, seen as a candidate with baseline competency.
• Eddie George, current head coach at Bowling Green and former Titans player, seen as a long-shot but a fan favorite candidate.
• Josh McCown, QB coach with the Minnesota Vikings seen as a potential future head coach.

The Titans are taking their time to conduct a thorough search, as the decision is critical for the future of their young quarterback Cameron Ward and the franchise's long-term success with a new stadium opening soon.

In summary, Mike McCoy is the interim coach currently, and the candidates most frequently mentioned for the permanent role include Kliff Kingsbury, Joe Brady, Matt Nagy, Mike Kafka, and Mike McCarthy among others.
