Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 players each, who primarily use their feet to propel a ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposing team by moving the ball beyond the goal line into a rectangular-framed goal defended by the opposing team. Traditionally, the game has been played over two 45-minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries and territories, it is the world's most popular sport.
"Power play" is a sporting term used to describe a period of play where one team has a numerical advantage in players, usually due to a rule violation by the opposing team.
Indoor soccer or arena soccer is a five-a-side or six-a-side version of minifootball, derived from association football and adapted to be played in walled hardcourt indoor arena. Indoor soccer, as it is most often known in the United States and Canada, was originally developed in these two countries as a way to play soccer during the winter months, when snow would make outdoor play difficult. In those countries, gymnasiums are adapted for indoor soccer play. In other countries the game is played in either indoor or outdoor arenas surrounded by walls, and is referred to by different names.
A penalty in ice hockey is a punishment for an infringement of the rules. Most penalties are enforced by sending the offending player to a penalty box for a set number of minutes. During the penalty the player may not participate in play. Penalties are called and enforced by the referee, or in some cases, the linesman. The offending team may not replace the player on the ice, leaving them short-handed as opposed to full strength. When the opposing team is said to be on a power play, they will have one more player on the ice than the short-handed team. The short-handed team is said to be "on the penalty kill" until the penalty expires and the penalized player returns to play. While standards vary somewhat between leagues, most leagues recognize several common varieties of penalties, as well as common infractions.
The penalty box or sin bin is the area in ice hockey, rugby union, rugby league, roller derby and some other sports where a player sits to serve the time of a given penalty, for an offence not severe enough to merit outright expulsion from the contest. Teams are generally not allowed to replace players who have been sent to the penalty box.
International rules football is a team sport consisting of a hybrid of football codes, which was developed to facilitate international representative matches between Australian rules football players and Gaelic football players.
Rugby league nines is a version of rugby league football played with nine players on each side. The game is substantially the same as full rugby league, with some differences in rules and shorter games. Nines is usually played in festivals, as its shorter game play allows for a tournament to be completed in a day or over a single weekend.
A rugby league team consists of 13 players on the field, with 4 substitutes on the bench. Each of the 13 players is assigned a position, normally with a standardised number, which reflects their role in attack and defence, although players can take up any position at any time.
In sports, a time-out or timeout is a halt in the play. This allows the coaches of either team to communicate with the team, e.g., to determine strategy or inspire morale, as well as to stop the game clock. Time-outs are usually called by coaches or players, although for some sports, TV timeouts are called to allow media to air commercial breaks. Teams usually call timeouts at strategically important points in the match, or to avoid the team being called for a delay of game-type violation, such as the five-second rule in basketball.
In sports, an ejection is the removal of a participant from a contest due to a violation of the sport's rules. The exact violations that lead to an ejection vary depending upon the sport, but common causes for ejection include unsportsmanlike conduct, violent acts against another participant that are beyond the sport's generally accepted standards for such acts, abuse against officials, violations of the sport's rules that the contest official deems to be egregious, or the use of an illegal substance to better a player's game. Most sports have provisions that allow players to be ejected, and many allow for the ejection of coaches, managers, or other non-playing personnel. In sports that use penalty cards, a red card is often used to signal dismissals. In some sports, another player is permitted to enter the game in place of the player who has been ejected, but in others the team is required to continue the game with a reduced number of players.
In association football, a substitute is a player who is brought on to the pitch during a match in exchange for an existing player. Substitutions are generally made to replace a player who has become tired or injured, or who is performing poorly, or for tactical reasons. A player who has been substituted during a match takes no further part in the game, in games played under the standard International Football Association Board Laws of the Game.
Interchange is a team position in Australian rules football, consisting of players who are part of the selected team but are not currently on the field of play.
Penalty cards are used in many sports as a means of warning, reprimanding or penalising a player, coach or team official. Penalty cards are most commonly used by referees or umpires to indicate that a player has committed an offence. The official will hold the card above their head while looking or pointing toward the player who has committed the offence. This action makes the decision clear to all players, as well as spectators and other officials in a manner that is language-neutral. The colour or shape of the card used by the official indicates the type or seriousness of the offence and the level of punishment that is to be applied. Yellow and red cards are the most common, typically indicating, respectively, cautions and dismissals.
The National Hockey League rules are the rules governing the play of the National Hockey League (NHL), a professional ice hockey organization. Infractions of the rules, such as offside and icing, lead to a stoppage of play and subsequent to the offending teams. The league also determines the specifications for playing equipment used in its games.
