What should be done if a team requests a late substitution during a set?

In the context of volleyball, the rules regarding substitutions are quite strict due to the need for maintaining the flow of the game and ensuring fairness. A late substitution request typically means that the request is being made at a time when it is not allowed according to the game regulations. Therefore, if a team requests a substitution too late in the set, it must be refused in order to adhere to the established rules and maintain the integrity of the match.

This is important for ensuring that all teams understand and follow the same rules, which prevents any advantage that could be gained by allowing late substitutions. Such adherence ensures fairness for both teams and upholds the spirit of the competition. It is crucial for players, coaches, and officials to be aware of and respect these time constraints to ensure that the game proceeds smoothly and within the official guidelines.
