Reed worked out with the Titans on Tuesday, Tom Pelissero of NFL Network reports.
With Jadeveon Clowney (knee) and Jayon Brown (elbow) out for the foreseeable future, the Titans could potentially look to the veteran Reed for some assistance. Reed played nine games for the Cardinals last season, recording eight tackles and one sack. Before that, he played eight seasons with the Falcons and Texans.
