Dean Pees is coming out of retirement to join Arthur Smith's coaching staff with the Atlanta Falcons as the team's defensive coordinator, the team announced Thursday.
The Falcons also named Dave Ragone as offensive coordinator and Marquice Williams as special teams coordinator.
Pees' second retirement lasted just more than a year after he walked away from the Tennessee Titans following the 2020 season.
He has 47 years of coaching experience, including 16 NFL seasons.
Pees, 71, retired for the first time after the 2018 season when he left after six seasons with the Baltimore Ravens.
