Mack signed a contract with the Titans on Thursday, Turron Davenport of ESPN.com reports.
Mack missed last season after being cut from injured reserve by the Packers after suffering an undisclosed injury. The 26-year-old has bounced around the league since being selected in the seventh round of the 2019 Draft by the Saints, but he has yet to play in a regular season game. He'll work to finally make that happen with the Titans in 2023.
