Douglas (concussion) wasn't practicing Tuesday, Doug Kyed of the Boston Herald reports.
Douglas has yet to mix into drills since suffering a concussion during a Week 12 loss at the Giants, giving him very little leeway to put himself in a position to play Thursday in Pittsburgh. It remains to be seen how much of the rest of the team's receiving corps will be available considering DeVante Parker (knee), JuJu Smith-Schuster (ankle) and Kayshon Boutte (shoulder) all are tending to health concerns as well.
