Fairley was in full uniform and went through position drills, according to MLive.com. Media members aren't allwoed to observe team drills, per team policy, and the extent of his participation was undisclosed.
Fairley, the No. 12 overall pick in April's draft, broke his foot during training camp and hasn't played so far this season, including preseason games.
Schwartz cautioned that even if Fairley makes his debut again the Bears, expectations should be minimal.
"I think when we do get him back, there will be a progression to that," Schwartz told MLive.com. "You're talking about a guy that played in zero preseason games, and you always have a progression with those. We won't go from zero to 100 without taking some steps along the way."
