Pittman (right leg) didn't practice Tuesday, Alan Saunders of SteelersNow.com reports.
The same applies to fellow WR DK Metcalf (undisclosed), according to QB Aaron Rodgers. As a result, there's a decent chance that both Pittman and Metcalf are held out of Thursday's preseason opener against the Packers, but there's been nothing so far to suggest that either player is managing anything too concerning.
