Should I play netball or soccer?

I played soccer last season, and before that I never got into the netball team. My friend is on the school Netball team, and so I was waiting for her after school. They were training, and having a mini match, and there was an uneven number of girls, so the coach asked me to play. There were other girls there too, and she only really knows me from softball, so she said: Once sporty, always sporty, and threw me a WD bib. I really loved netball, and I'm good at getting the ball off people because of height advantage and soccer. But the thing is, I'm only allowed one sport and I already chose soccer because I knew I'd get in. But I was injured so many times last week I don't really want to play. And the *****y girls are on the soccer team. I LOVE netball, so should I ask the netball coach to try and slot me in as a reserve on the team? Or would she reject me? Or should I keep playing soccer?
