The tweet was shared when the Golden Knights were up 4-0 during the second period. It featured a GIF of a Canucks player smashing his hockey stick in anger while seated on the bench. 

The teams face off again on Tuesday, August 25, so the Canucks will have a shot to get even with the Golden Knights. 

Regarding the loss, the Canucks' coach, Travis Green, said, "I’ve got a lot of belief in our group, whenever we’ve challenged them to respond, they always come with a great effort."
