However, Rugby is one of the few sports that has "Blood Substitutions". these are used when a player is, as the name suggests a bleeding injury. the referee will stop the clock/match and ask for the injured player to be taken off and a replacement (normally for that position) to replace them until the wound can be stitched, stapled and covered to prevent further blood loss.
