Well, in minor hockey, I'm 36 now, so, say 28 years ago.... bruised a rib blocking a shot.
In more recent years, playing rec league hockey:
Badly bruised thumb getting hit with a slapshot from my teammate, going to the net...
hit in the mouth with puck, cut lip pretty good
sprained knee a few times, need a brace
puck rolled up my stick cut me on the eyebrow on the left eye
puck deflected hit me in the right eye, needed 7 stitches to close it right on my eyelid near the tearduct. Stitches rubbing your eye are annoying!
worst one: some wannabe tough guy puts me in a head lock from behind and drives me head first into the ice resulting in me beign totally disoriented, talking nonsense, not knowing how I go the arena/who I came with, etc.... so, suspected concussion, plus I had a rocking headache for days.
