In the Australian Football League (AFL), each team fields 22 players during a match. This includes 18 players on the field and 4 players on the interchange bench, who can be rotated in and out of the game. The interchange system allows teams to manage player fatigue and injuries effectively throughout the match. Additionally, teams typically have a squad of 30 players, which includes the 22 active players for each game and 4 reserves who can be called upon if needed due to injury or other circumstances. This structure is designed to maintain a high level of competition and player performance throughout the season.
It's important to note that while the standard number of players is 22, variations can occur in different leagues or formats of Australian rules football, but the AFL's regulations are widely recognized as the standard for professional play. The rules regarding team composition and player interchange have evolved over time, but the current format has been in place for several years, ensuring consistency across the league.
