The Titans hosted Mapu for a workout Tuesday, Aaron Wilson of KPRC 2 Houston reports.
Mapu was waived from the Texans' IR with an injury settlement in late August due to an undisclosed injury. The linebacker is now healthy and ready to return to the NFL. The Titans' defense is thin at linebacker, and the Patriots' 2023 third-round pick could have a shot to revive his career in Tennessee.
