As the Flames were trailing by three goals, the game got heated in the waning minutes of the frame. A heavy-weight tilt broke out at 16:24 between Flames' winger Milan Lucic and Kurtis MacDermid, who were both sent off for the remainder of the frame.
Just a few seconds after the exchange, Cogliano was called for tripping at 16:29. On the Flames' power play, Georgiev made a pad save on a Rasmus Andersson shot. The rebound kicked out to the goal line and - from a sharp angle - Toffoli corralled the puck off his skate and zipped a shot past the Avalanche netminder to trim Calgary's deficit down 3-1.
Early in the third period, Colorado upped its lead 4-1 on a highlight-reel goal from Malgin at 4:12. The Swiss forward collected a pass from Josh Manson in the neutral zone. From the center-ice logo, Malgin carried the puck up ice, deked past three Calgary skaters as he used a head fake, skated into the low slot and snapped a wrist shot past Markstrom.
