This is what I did.

Well since there was 2 girls who needed shirts, one was given by a member of there team, after a short pause and my anticipation that another girl from there team would give up their shirt, I waited, but then I gave up mine. After running to the side line feeling really naked, I found someone who had an extra shirt I could wear.

I must also say that I am amazing and with the help of spray n' wash got all the blood out.
