Too many men

Too many men is a penalty that may be called in various team sports when the team has more players on the field or other playing area than are allowed by the rules. Penalties vary from one sport to the next.

In association football, if a team is found to have more than 11 players on the field, the referee must determine which is the extra player, and the player so determined is given a yellow card.

In Australian rules football, the primary means for controlling interchanges in most leagues is the head count. At the request of a team captain, the umpire will instruct all players from both teams line to line-up in the centre of the ground, and the umpire will then count the players. If either team is found to have more than eighteen players on the field, the team's entire score to that point of the game is cancelled, except if that team's score was zero points at the time of the head count.

Since 2008, in the top level Australian Football League, the interchange steward monitors player interchanges, and informs the emergency umpire directly if a team has more than eighteen men on the ground due to an interchange error. When an infringement is identified in this manner, a free kick and 50-metre penalty are awarded to the opposing team at the centre of the ground, but the team's score is not cancelled because infringements are usually noticed quickly, minimizing the potential influence on the game.

Baseball limits teams to one pitcher, four infielders, three outfielders, and one catcher (nine players) on the defense at any time. If the defense has more than nine players on the field at any time, the umpire must determine who is the tenth player, and that player is ejected from the game.

Professional and collegiate basketball (both men's and women's) limit teams to five players on the court at any one time. A team with more than five in play at once is assessed a technical foul for Too Many Players on the Court. In March 2009, the National Basketball Association rules were changed to allow for the nullification of goals scored with too many players on the court. Under no circumstance can any player or coach be ejected on a technical foul caused by too many players.
