The Titans (0-3) signed Jones this offseason, then cut him Sept. 4. But using rookies as their returners resulted in two turnovers and 14 points in last weekend's 24-17 loss to the New York Jets.
They gave Jones a physical Tuesday and signed him back to the roster.
Tennessee placed veteran punter Craig Hentrich on injured reserve. He strained a calf muscle Sept. 20. Running back Chris Henry was released from the roster with running back Rodney Ferguson cut from the practice squad.
