Related to this sudden reversal of decision that surprised everyone in the Bell Centre, including Marc Denis and Pierre Houde, the head coach of the Canadiens provided explanations on what actually happened with the referees.
In short, according to one of the officials, it was so loud at the Bell Centre that he heard "good goal" instead of "no goal".
Fortunately for the CH, this situation did not affect the team's morale, who scored another goal a few seconds later, thanks to captain Nick Suzuki.
