On Feb. 15, 2004, league-leading scorer Markus Näslund (a member of the Vancouver Canucks) was injured by Colorado Avalanche center Steve Moore.
Many of Näslund's teammates thought it was a cheap shot and were very upset about it, especially Todd Bertuzzi, who called Moore "a piece of sh*t."
Less than a month later, the two teams played again without incident. However, five days later, when they played once more, Vancouver was a lot more physical.
There were four fights in the first period alone.
By the time the third period began, the Avalanche had already run away with the game, and the Canucks clearly weren't happy.
Midway through the third period, Bertuzzi began stalking Moore around the ice attempting to provoke him into a fight, but Moore refused.
Bertuzzi proceeded to sucker punch him. Moore then fell to the ice, where several other players fell on top of him.
Moore was carried off on a stretcher and sent to the hospital, where he was treated for three fractured vertebrae in his neck, a grade three concussion, vertebral ligament damage, stretching of the brachial plexus nerves and facial lacerations. He was also suffering from amnesia.
He never played another game in the NHL.
