The Titans signed Adams to their active roster off the Steelers' practice squad Wednesday, Terry McCormick of TitansInsider.com reports.
The Titans recently placed A.J. Moore (ankle) on injured reserve, so Adams will provide added depth to Tennessee's secondary. Adams has 190 career tackles, seven interceptions and two forced fumbles over six seasons, but he saw a decreased role with Tampa Bay in each of the last two campaigns.
