The Tennessee Titans continue to make depth additions to their roster as training camp kicks off in Nashville. The Titans announced that they have signed former Atlanta Falcons defensive tackle Timmy Horne to a deal after hosting him for a workout. Tennessee also signed former Detroit Lions running back Jermar Jefferson to a contract. Horne, 27, spent last offseason with the New York Giants but suffered a torn Achilles in the team’s final preseason game.
