If this is accurate, looking at the other teams' early-March schedules, it will probably be the make-up date for the Oilers game. I'd guess on March 7.
The Flames are in Colorado on the 5th and at home against Washington on the 8th. The Oilers are in the middle of a long home stand then, and off on the 6th, 7th, and 8th.
