The Avalanche will be without leading scorer Nathan MacKinnon for two to four weeks with an upper-body injury. On the team’s Twitter account Thursday, coach Jared Bednar said of MacKinnon’s absence: “It’s not a great feeling when you lose a guy like that because of what he means to our team. But I’m excited for the opportunity it presents other guys.”

MacKinnon was hurt in the second period Tuesday against the Canucks after a collision near the end boards. He was sent back to Denver to be evaluated as the team continued its trip.
