Soccer Rules Practice Exam

A player must be substituted primarily when they are injured or when tactical adjustments are necessary. This aligns with the rules governing substitutions in soccer, which prioritize player safety and the strategic elements of the game. An injury to a player can necessitate a substitution to ensure that the player receives proper care and the team does not continue with a player who may be unable to perform effectively. Additionally, tactical adjustments can require substitutions to bring in players who can better meet the demands of the game situation, whether that be for defensive reinforcement, adding offensive power, or changing formations.

In contrast, the other scenarios do not inherently require a substitution. The occurrence of a goal by the opposing team does not mandate a substitution, although teams may choose to make tactical changes in response. Similarly, substitutions are not automatic at the end of each half; they occur based on specific circumstances and coaching strategy rather than a fixed schedule. Lastly, while a coach does have the authority to decide when substitutions occur, it's not solely tied to their decision. Players must be substituted for valid reasons such as injury or tactical need, rather than being arbitrary choices.
