Forwards Artturi Lehkonen (upper body) and
Jean-Luc Foudy
(lower body) each did not play against the Flyers.
Lehkonen was injured during the first period of the Avalanche's 5-1 loss at the Bruins on Saturday and is day to day.
Foudy came out briefly during the morning skate and is also day to day.
Lehkonen is fourth on the Avalanche with 18 points (seven goals, 11 assists) in 22 games.
"We're going to miss him," coach Jared Bednar said. "Obviously missed him last game. But it just is what it is. Hopefully he's back sooner rather than later."
Foudy, who was called up from Colorado of the American Hockey League on Nov. 28 and made his NHL debut the next day, does not have a point in three games.
They join a crowded Avalanche injury list that includes forwards Valeri Nichushkin (ankle), Evan Rodrigues (lower body), Shane Bowers (upper body), and defensemen Josh Manson (lower body), Bowen Byram (lower body) and Kurtis MacDermid (lower body). In addition, forwards Gabriel Landeskog (knee) and Darren Helm (hip) have yet to play this season with each recovering from offseason surgery.
Nathan MacKinnon left the game Monday in the first period because of an upper-body injury. There was no update after the game.
"It takes a little bit more from everyone involved when you're down a bunch of guys, so staying mentally tough and sort of letting the positivity shine through I think is really important," Bednar said.
Forward Charles Hudon, who was recalled from the AHL on Sunday, played his first NHL game since March 10, 2020, with the Canadiens. He had 16 points (eight goals, eight assists) in 20 AHL games this season. -- Adam Kimelman
