Vancouver Canucks defender gets Knocked Out after taking a hit to the head

Some really unfortunate luck for Mark Friedman of the Vancouver Canucks last night. During a game against the Colorado Avalanche, Friedman got tangled up with Valeri Nichushkin in front of Colorado's net. After a push in the face from Nichushkin's stick, Friedman started falling backwards. While doing so, a puck shot by a teammate may have hit him or Nichushkin. It's tough to tell. However, Friedman's head hit the ice hard.
