Marchand was a full participant in Wednesday's practice as he continues to work his way back from elbow, groin and abdominal surgery, per Steve Conroy of the Boston Herald.
Marchand also skated with the Bruins on Tuesday, but he was wearing a non-contact sweater at that time. The 36-year-old had 29 goals and 67 points in 82 regular-season contests last year and is expected to continue to serve in a top-six capacity in 2024-25.
