8:15pm: Bill Callahan is indeed expected to draw interest from another team before the end of the season, per Sports Illustrated’s Albert Breer.
4:56pm: In the wake of Brian Callahan‘s firing, it was unclear who would take over head coaching duties for the remainder of the campaign. The Titans now have an internal replacement in place. 
Senior offensive assistant Mike McCoy is being promoted to interim head coach, as first reported by NFL Network’s Tom Pelissero. McCoy has head coaching experience at the NFL level, so he was regarded by many as the top internal candidate to replace Callahan. As such, this move (which is now official) comes as little surprise.
McCoy, 53, coached the Chargers from 2013-16. That span began with two straight 9-7 campaigns but ended with records of 4-12 and then 5-11. Callahan managed a mark of just 4-19 during his time with the Titans, but the team will hope for a turnaround of some kind under a more experienced staffer.
McCoy returned to his role as offensive coordinator of the Broncos after his Chargers tenure ended. That lasted one season and was followed by another one-and-done run in an OC capacity with the Cardinals. McCoy worked as the Jaguars’ quarterbacks coach for three seasons before the arrival of a new regime this winter led to a number of changes. That resulted in his Titans gig, one which will now consist of head coaching duties to close out the year.
Tennessee struggled on both sides of the ball last season under Callahan, and the first six games of 2025 has not yielded much in the way of progress. Quarterback Cam Ward will look to continue developing during his rookie season, but he has already witnessed a change in offensive play-caller and now a switch at the head coaching spot. McCoy will aim to offer stability over the coming weeks while the search for a full-time head coach (presumably) begins.
In other coaching news, veteran Titans reporter Paul Kuharsky reports offensive line coach Bill Callahan – Brian’s father – is expected to resign. The elder Callahan is highly experienced, particularly working with O-linemen at the NFL level, and he has operated as an interim head coach in the past. With his son having been dismissed, however, Bill’s future will be something to watch closely.
Turnover in multiple levels of the organization has been a constant for the Titans over the past few years. That has included multiple GM changes and a short-lived attempt to replace Mike Vrabel following his dismissal. Vrabel and the Patriots will visit Tennessee in Week 7, McCoy’s first action as an NFL head coach in nine years.
