The Colorado Avalanche have been hit with a big injury blow as their center and leading scorer Matt Duchene is out for four weeks with a knee injury.
Duchene was injured in Colorado's 3-2 victory over the San Jose Sharks on Saturday after colliding with team-mate Jamie McGinn.
Duchene has 23 goals and 47 assists in 71 games for the Avalanche this season and has helped them get into their current position of second in the Central division.
They are currently one point ahead of the chasing Chicago Blackhawks but have two games in hand on the current Stanley Cup champions.
The injury means that Duchene is going to miss the final eight games of Colorado's regular-season and most likely, the first round of the Stanley Cup play-offs.
Rookie Nathan MacKinnon will replace Duchene at center for their game against the Columbus Blue Jackets on Tuesday night.
MacKinnon leads all NHL rookies on goals, assists and points and is a good option for coach Patrick Roy to move from Right wing to center.
