Avalanche forward Milan Hejduk missed Colorado's game against the Calgary Flames last night with a knee injury.
Hejduk has missed five games this season, two with a balky back and three more with a knee ailment. He is tied for the team lead with 12 goals.
The team also was without right winger Marek Svatos, who is hampered by a groin injury.
Colorado coach Joe Sacco said both players are day-to-day. The Avalanche play again tomorrow against Washington.
The defending Stanley Cup champion Pittsburgh Penguins played their first game this season with their entire lineup healthy on Saturday night, beating the Florida Panthers, 3-2.
Nine regulars missed time over the team's first 32 games, including five defensemen, and as many as six players at once were missing from the Penguins' lineup.
The Los Angeles Kings, who have not made the playoffs since 2002, have 45 points and are just one point behind the Washington Capitals for the NHL's best record.
The Kings are 7-0-1 in their last eight games and 21-10-3 overall.
Last season, Los Angeles did not get its 21st victory until Feb. 3.
Saturday's 3-2 loss to Buffalo marked the 15th time in their last 19 games that the New York Rangers scored two or fewer goals.
