NEW YORK (Dec. 17, 2021)- The National Hockey League announced today that it has extended the period of game postponements for the Calgary Flames through their game previously scheduled for Dec. 23 against Seattle. Additionally, due to concern with the number of positive cases within the last two days as well concern for continued COVID spread in the coming days, the Colorado Avalanche's and Florida Panthers' games also will be postponed at least through the scheduled completion of the League's Holiday Break in the schedule on Dec. 26. The decision was made by the NHL's, the NHLPA's and the Club medical groups.
