Martin (hamstring) did not participate in Friday's practice, ESPN's Jenna Laine reports.
Martin was present for Friday's practice, but did not have pads nor a helmet, indicating he will remain sidelined. He'll have one more chance to practice this week with the Buccaneers playing Monday night, but Martin has not practiced since injuring his hamstring in Week 2. He'll likely have to get some practice work in Saturday to have any chance of playing in Week 5.
