Pickens (hamstring) was listed as a non-participant for Tuesday's walk-through practice, Teresa Varley of the Steelers' official site reports.
According to Mike DeFabo of The Athletic, Pickens was spotted taking part in individual drills off to the side during the portion of the walkthrough that was open to the media, while Alan Sauders of SteelersNow.com adds that Pickens also took part in a ball-security drill with teammates. The wideout will likely need to mix into more on-field drills as the week progresses in order for the Steelers to feel confident in his availability for Saturday's game in Baltimore.
