I used to play as a number 8 at Blackheath Rugby Club. I got a range of injuries over the years, a dislocated clavicle, a broken finger, twisted ankle, and a range of cuts and bruises. I chose to play the game and injuries were part of that choice.
I understand that steps must be taken to prevent unnecessary harm but we cannot avoid all danger in life, it would create a life not worth living. Rugby is a tough came, if you are a bit soft I recommend you play in the backs, if you are very soft indeed try football, or tiddly-winks (although those counters can take your eye out!).
