I've seem some gruesome injuries playing hockey over the years. Ankles bent in weird angles, bones popping out out arms, shins, eye gouges (yuck), accidental stick in eye + blindness and some nasty, nasty cuts.

The Malarchuk slice was the worst, the Zednik one I only saw a bad quality version but it happens more often than you guys realize.

Neck guards should be mandatory in the NHL but it will never be until someone dies. The macho mentality is great in this sport.
