Martin (concussion) wasnt present for Friday's practice, Greg Auman of the Tampa Bay Times reports.
Unless Martin gets in some on-field activity in the closed portion of Friday's session, he'll go down as a non-participant in practice for the third day in a row. With that in mind, it's looking unlikely that he'll clear the concussion protocol before Sunday's game against the Packers, but the team should provide an update on his availability one way or the other shortly after Friday's practice. A backfield committee of Jacquizz Rodgers, Charles Sims and Peyton Barber would likely be on tap if Martin is sidelined Week 13.
