"wrestling herpes" is actually a somewhat common thing. however, if your school or coach doesn't do anything to prevent it (i.e. makes sure the wrestling area is clean, informing the players of safe and proper hygiene, etc.) it might not be worth the risk. i'm surprised the parents haven't voiced their outrage by not.
i'd say tell your parents to call the school about it. make sure the school knows they should be doing more to protect the students. have them call the other parents and tell them to do the same as parents of high school athletes so often do.
by next season your collarbone should be healed up nicely and (hopefully) there will be a safer environment and you'll be fine.
Yes you can watch it if you are bored or want to pass your time
you're sawft
