Martin said after Sunday's loss in Arizona that he's tending to a "slight tweak" of his hamstring, Roy Cummings of WFLA News Channel 8 reports.
With an initial prognosis of doubtful (then no potential) to return, Martin is seemingly dealing with a more severe injury than his contention, but time will tell whether any DNPs come to pass. If he ultimately trends toward inactive status next Sunday against the Rams, Charles Sims would be next in line for touches.
