Landeskog, who was activated from the injured reserve ahead of Game 2 Monday, took to the ice for warmups but was scratched from the lineup. Dallas won 4-3 in overtime to even the series 1-1.
The Swedish star has battled knee injuries for the past three years and has had two surgeries along the way.
He hasn’t played in the NHL since June 26, 2022, when Colorado defeated the Tampa Bay Lightning to capture the Stanley Cup.
Landeskog rejoined the Avalanche last week for practice after a two-game rehab stint in the American Hockey League.
The 32-year-old has 571 points (248 goals, 323 assists) in 738 games over 11 seasons with the Avalanche. He also has 67 points (27 goals, 40 assists) in 69 playoff games.
