The Titans signed Hallett from the practice squad to the active roster Saturday.
Hallett was elevated to the active roster in consecutive weeks, playing 11 defensive snaps and 39 special-teams snaps as the backup strong safety. With Kendell Brooks (undisclosed) on IR for at least another two games, Hallett will continue to support the Titans' secondary behind Amani Hooker while holding onto his last practice squad elevation.
