The Tennessee Titans, perhaps searching for depth for their defensive line, signed free-agent DL Marques Douglas. To make room for him on their 53-man roster, the team waived DT Amon Gordon.

Douglas, 33, recently worked out for the Titans.

The defensive lineman has played most of his career in the 3-4 defense, but Tennessee plays a 4-3, so he might get time at end and tackle.
