In football, each team is allowed to make up to three substitutions during a match. This means that a total of six players can be replaced during the game. However, in some competitions or tournaments, such as the FIFA World Cup, teams may be given an additional substitution opportunity during extra time. It’s important to note that the number of substitutions may vary depending on the specific rules of the competition.
