GAME RECAP

What happened: The Avalanche closed a disappointing road trip at 1-3. Their injury plagued roster now resembles an American Hockey League team.

What went right: Alex Newhook opened the game with a power-play goal and scored again in the third period. He took a puck off the face on a Cale Makar third period shot but returned to play. Charles Hudon — a longtime Canadiens forward (2015-20) — made his Avalanche debut after being called up from the AHL. Coach Jared Bednar said: “Noticeably one of our best forwards.” Mikko Rantanen scored his 15th goal of the season.

What went wrong: Nathan MacKinnon left the game with an upper- body injury in the first period and was ruled out for return. Philadelphia — a bad team in a rebuilding phase — scored four unanswered goals (twice on power- play chances). The Avs were unable to capitalize on momentum after consecutive goals scored late in the third period. The Flyers potted an empty- netter to close the game.

Between the pipes: Avs goalie Alexandar Georgiev made 29-of-33 saves. Flyers’ netminder Carter Hart finished with 29 stops on 32 Colorado shots on goal.

What’s next: T The Avalanche (13-9-1) return home Wednesday to face the Boston Bruins.
