Shaw was in Montreal's active lineup Friday for the first time since being claimed off waivers. He had one hit and one blocked shot in 10:36 of ice time in a 3-2 win over Washington.
Shaw can help the Canadiens at the margins, but not in the area of most obvious need: goal scoring. He'll give them a stable fourth-liner who will get time on the penalty-kill unit. Shaw replaced Daniel Carr in the lineup Friday.
