You can nominate two replacement athletes—one male and one female. These replacements may include players not officially registered in any category or players already registered in another category. If a player is already registered in another category, they can only be substituted if they do not participate in more than two categories in total. A replacement player can only be used if the on-site medical team confirms that the injured athlete is unable to continue competing.
Substitution is permitted only during group matches, exclusively in the doubles category, and only in cases of injury.
