I was reading the 11th edition draft, and noticed section VI C 7. (which is the same in the 10th as VI C 6)
"Any player may call an injury time-out for a player who is bleeding or has an exposed open wound"
I also noticed VI C 1
"Any player on the injured player's team may call an injury time-out"
Playing devil's advocate, does this mean if an opposing player trips and knocks herself unconscience, and nobody notices her (e.g. because everyone else is down the field), I can't call an injury time-out? Common sense say otherwise, but potential heartless rule sticklers may exist.
