Lehkonen had three shots on net and one hit over 12:53 of ice time in Tuesday's 2-1 win over the Flames.
Lehkonen, who was acquired from the Canadiens at the trade deadline, finally made his debut for the Avalanche after dealing with visa issues. He skated on the second line, which was reworked with Nazem Kadri moving up to the top line to replace the injured Nathan MacKinnon (upper body). Lehkonen could move around the depth chart, as he often did for Montreal.
