Lambo signed with the Titans' practice squad Tuesday, Jim Wyatt of the team's official site reports.
Lambo will serve as an emergency option for the team, as Randy Bullock is dealing with a calf issue that he suffered in warmups of Week 10's win over the Broncos. Despite Bullock's ability to play through the injury Sunday, he is considered questionable for Thursday's game with the Packers. If he is unable to play, Lambo will now be in line to handle kicking duties.
