New York Giants coach John Harbaugh has reportedly filled the last major vacancy on his coaching staff by hires Brian Callahan as quarterbacks coach and passing game coordinator.
Callahan was fired as head coach of the Tennessee Titans midway through the 2025 season with the team at 1-5. In over one season as Tennessee’s head coach, Callahan went 4-19.

Callahan served as the quarterbacks coach for the Detroit Lions in 2016 and 2017, then served in that role for the Oakland Raiders in 2018. He was the offensive offside calling coordinator for the Cincinnati Bengals from 2019-2023 before becoming the head coach at Tennessee.
Callahan worked with Peyton Manning as a young assistant coach with the Denver Broncos, Matthew Stafford with the Lions, Derek Carr with the Raiders and Joe Burrow with the Bengals.
This creates a strange dynamic where Callahan, the former Tennessee head coach plays a key role on the Giants staff and former Giants head coach Brian Daboll is now the Titans offensive coordinator.
The Giants have surrounded second-year quarterback Jaxson Dart with experienced coaches such as offensive coordinator Matt Nagy, senior offensive assistant Greg Roman and now Callahan.
