Hi, I am 15 in Year 11. I am 170 cm's and 57 kilos. Would be playing Rugby Union for the first time. Am i to small? Or like not suited for the game?

Actually,if your small and not buff,they will not take you into the team as they don't want u to get hurt. Being buff and stealthy at the same time is required for rugby

You're perfect man

At your age anything goes. I've seen very small kids play on the outsides out wide and run fast...you will put on muscle the more u play
