The Canucks were able to score once during the five-minute power play they were given.
Roussel went down shortly after the Pettersson play.
Lemieux was assessed a match penalty for what was deemed an illegal hit to the head. A puzzling call as it appeared Roussel simply skated, tripped and fell awkwardly into Lemieux rather than Lemieux initiating the contact.
As you can see in the video at the top of the page, Roussel then landed awkwardly on his right leg when he hit the ice.
Pettersson eventually returned to the Canucks bench after a trip to the dark room, but Roussel will miss the rest of the season with a knee injury.
