Hampus Lindholm, out since Nov. 12 with a lower-body injury, was also a full participant in practice for the first time since going down in St. Louis after taking a shot off the knee. Like McAvoy, he will not travel to Buffalo but is closing in on a return to game action.

Charlie McAvoy and Hampus Lindholm both returned to Bruins’ practice on Monday. Neither will play on Tuesday at Buffalo, but their return signals a significant step in their efforts to return to the lineup.
