The Tennessee Titans have fired head coach Brian Callahan following a disappointing 1-5 start to his second season and a 4-19 overall record. Callahan, a former Bengals offensive coordinator, has become the first NFL head coach to be dismissed this season. This decision has sparked discussions on potential replacements, with several candidates being considered, including Kliff Kingsbury and Matt Nagy. The Titans are now searching for an interim head coach as they look to turn their season around amidst continuing organizational struggles.
