Buccaneers' Doug Martin: Doubtful to return Sunday

Martin is doubtful to return to Sunday's game at Arizona as a result of a hamstring injury.

Analysis:

When Martin left the field early in the second quarter, he was "dragging his leg a little," according to Kevin O'Donnell of FOX 13 Tampa Bay. Although the Buccaneers have yet to pin down a diagnosis, Martin is an unlikely candidate to make another appearance in Week 2. Dominating the carries with seven for 23 yards prior to his departure, he'll thus hand off primary RB duties to Charles Sims.
