Stewart (hamstring) is expected to play some time this preseason, the Panthers' official Twitter account reports. Stewart has been sidelined for the past couple weeks due to a pulled hamstring, but is apparently expected to return to action in the near future. Entering the regular season back healthy would be a welcomed accomplishment for Stewart, who has missed 17 games over the past two seasons. Whenever he re-joins his teammates in practice, Stewart figures to work in tandem with running back DeAngelo Williams.
