The Tennessee Titans are cutting ties with multiple members of the Callahan family. A day after firing Brian Callahan, the team announced it was parting ways with offensive line coach Bill Callahan, Brian’s father.

Titans interim head coach Mike McCoy made that announcement Tuesday. McCoy said Bill’s departure was the only coaching change on the staff.

The move doesn’t necessarily come as a surprise. Bill probably wasn’t too eager to stick around after the team fired his son Monday.

Bill, a long-time NFL coach, joined the Titans’ coaching staff shortly after the team hired Brian in 2024. Despite being under contract with the Cleveland Browns, Bill was allowed to leave the team to coach with his son.

Bill has been a consistent presence in the NFL since the 1995 season. After starting his NFL coaching career as an offensive line coach with the Philadelphia Eagles, Bill took over as the Oakland Raiders’ offensive coordinator.

He was eventually promoted into a head-coaching role with the Raiders, leading the team to a 15-17 record before he was fired after the 2003 season. Bill then spent the next four seasons coaching Nebraska.

He returned to the NFL in 2008, and has filled a variety of coaching roles with five teams since then. Bill briefly got another head-coaching opportunity in 2019, taking over in Washington after Jay Gruden was fired. Bill led the team to a 3-8 record down the stretch, and the franchise opted to go in a different direction in the offseason.

Given his knowledge and experience coaching offensive linemen, Bill, 69, could still hook on with another team and continue his coaching career. Brian will likely also get another opportunity, though he may have to take a coordinator job after going 4-19 with the Titans.

Both men will likely have to wait until the offseason to find another opportunity.
