Landeskog, the Colorado captain, will be the first player from the 2011 NHL Draft to reach the 500-game mark and only the fifth draft pick to do so in Avalanche history (since 1995-96). The other skaters are Alex Tanguay (598), Matt Duchene (586), Paul Stastny (538) and John-Michael Liles (523).
The 25-year-old from Stockholm, Sweden, was drafted second overall by the Avs in 2011.
In 71 outings this season, Landeskog has recorded 57 points (24 goals, 33 assists), his most since 2014-15 when he registered 59 points (23 goals, 36 assists) while playing in all 82 games.
"What I have really liked about this year is he has been even-keel, his message has been the same all year long," Avalanche head coach Jared Bednar said of Landeskog. "Our feelings are the same about this team, that we have the ability to be a playoff team. We felt that from day one. That's the way that he has led our team and the way he has conducted his business all year long.
"His leadership and that of our core has been consistent. They have responded after losses most importantly, and after wins too. Not getting too high or too low, which is the same thing we are kind of going through right now and again last [game], it's a great response. It's a great bounce-back game, and it proves that we are a different club and that our leadership is strong."
