The 20-year-old forward likely was hurt when he was hit hard by the San Jose Sharks' Brad Stuart late in the first period of the Avalanche's game Saturday. Landeskog was skating through the neutral zone when Stuart stepped into him.
Landeskog returned to the game early in the second period and played 16:23, just two minutes below his season average.
In four games this season, Landeskog has one goal. As a rookie last season, he had 22 goals and 52 points while playing all 82 games.
I've never seen anything like that. The great thing is I don't know how many times guys bailed me out where they had to score to keep it alive and they did every time. It was amazing. It's not the way we draw it up, to go 20 rounds here, but obviously it's a big win.
