Galchenyuk, who was acquired from Montreal in a trade for forward Max Domi on June 15, 2018, appeared to have scored the tying goal on a power play at 16:21 of the third. However, Canadiens coach Claude Julien challenged that the Coyotes were offside on the play that led to the goal, and it was overturned after a video review.
"Obviously to have that goal called back is tough," Garland said. "We fought hard on that power play there. I think we used all two minutes of it to get that one, so to have it taken back stinks. But we fought hard this road trip, you know, losing (Ekman-Larsson) hurts for tonight but you know we did fight all the way through."
Canadiens captain Shea Weber credited Montreal's video coach for spotting the offside.
"That was huge," Weber said. "From the bench, it was tough to see. The guys on the ice said that they thought it was possibly off, but obviously he was paying attention, saw it right away, and I mean that's the difference in the game right there."
Drouin gave Montreal a 1-0 lead at 9:29 of the first period, taking a pass from Tomas Tatar and beating Pickard for his 14th of the season.
