1. Once a match has started, and a player gets injured, this should be recorded as a injury default loss. This match will be included in the player's ranking history as an injury default.
2. A match that is not played and hasn't started for any reason (injury or anything else) should be entered as a no show and won't be counted in the ranking.
3. It is the tournament director's decision as to whether a player who defaults a match due to an injury or no show, can continue to play in future matches in the tournament.
