I broke my nose in a hockey fight where the other guy grabbed my hair. That is also against the code. funny thing is was he was a good buddy growing up as we played hockey and baseball together at the rep team levels but in junior ended up on different teams when we were about 19 or 20. to this day he has no idea he broke my nose.
its all sideways looking up at it but straight on looks fine. He wasn't greasy or dirty. just a fight went sideways. I still won the fight if I recall as I always say I only lost one. Now I didnt have a whole lot over 3 years - maybe 12 fights including bench clearing brawls. I wasnt really tall or really strong but being quite bowl legged allows you to keep you balance in a fight
