Canucks goalie Roberto Luongo played the puck behind the net, dodging the Habs' Travis Moen on the penalty kill forecheck.
Jason Garrison picked up the puck then left it for Dan Hamhuis before the puck somehow found its way into Luongo’s crease. Luongo had his back turned when the puck deflected off his left skate, and then his right skate, and then into the back of the net.
The own goal gave Montreal a 2-1 lead and became the eventual game-winner in their 4-1 road win.
