The Tennessee Titans have a new head football coach.

Cincinnati Bengals offensive coordinator 39-year-old Brian Callahan has accepted the job offer.

Callahan started his NFL coaching career with the Denver Broncos in 2010. He became the Detroit Lions quarterbacks coach in 2016 for two seasons before moving to the Raiders in 2018. He’s spent the last five seasons as the offensive coordinator of the Bengals.

Callahan replaces Mike Vrabel who was 56-48 in six seasons as Titans coach.
