Martin (hamstring) has been ruled out for Thursday's game versus the Falcons, Jenna Laine of ESPN.com reports.
Initially slated to miss three weeks due to a hamstring injury, Martin suffered a setback during the Buccaneers' Week 6 bye, extending his DNP streak indefinitely. He'll thereby log his sixth absence in a row, and with Jacquizz Rodgers (foot) also sidelined, the Buccaneers will rely upon some combination of Peyton Barber, Antone Smith and Mike James out of the backfield.
