If a player in a Fours game becomes ill and must leave the green, what option is available?

In a Fours game, if a player becomes ill and must leave the green, the rules allow for a substitute to take the player's place. This practice is aligned with the guidelines set forth by the governing bodies of bowls to ensure that the game can continue fairly and without undue disruption. The use of a substitute allows for the continuity of the match and ensures that all participating teams can maintain the integrity of their competition.

Substitutes are typically required to be registered or qualified to play in the competition, allowing the team to fill the gap created by the ill player effectively. This mechanism is in place to promote fairness in the game while providing teams the opportunity to remain competitive even when unforeseen circumstances arise.
