Injured wide receiver Randy Moss, who took part in Sunday?s walk-through, was nowhere to be seen Monday once the pads came back on. ?He?s day to day,? coach Bill Belichick said. Moss suffered a left hamstring injury while chasing a Tom Brady bomb last Wednesday. He has appeared at a pair of walk-throughs since, but no practices - be they in pads or shells. It?s likely the Patriots are taking things cautiously with Moss, who has suffered hamstring and leg injuries in two of the last three seasons. He missed three games last year with the Oakland Raiders and there?s little incentive to play him in the exhibition opener Friday in Tampa against the Buccaneers.
