A referee is an official, in a variety of sports and competition, responsible for enforcing the rules of the sport, including sportsmanship decisions such as ejection.

Referees may be assisted by umpires, linesmen, timekeepers, touch judges, or video assistant referees.

The team captain of a football/soccer team, sometimes known as the skipper, is a team member chosen to be the on-pitch leader of the team; they are often one of the older or more experienced members of the squad, or a player that can heavily influence a game or has good leadership qualities.

The captain of a cricket team, often referred to as the skipper, is the appointed leader, having several additional roles and responsibilities over and above those of the other players. As in other sports, the captain is usually experienced and has good communication skills, and is likely to be one of the most regular members of the team, as the captain is responsible for the team selection. Before the game the captains toss for innings. During the match the captain decides the team's batting order, who will bowl each over, and where each fielder will be positioned. While the captain has the final say, decisions are often collaborative. A captain's knowledge of the complexities of cricket strategy and tactics, and shrewdness in the field, may contribute significantly to the team's success.
In cricket, the toss is the flipping of a coin to determine which captain will have the right to choose whether their team will bat or field at the start of the match.
Goalball is a team sport designed specifically for athletes with a vision impairment. Participants compete in teams of three, and try to throw a ball that has bells embedded inside of it into the opponents' goal. The ball is thrown by hand and never kicked. Using ear-hand coordination, originating as a rehabilitation exercise, the sport has no able-bodied equivalent. Able-bodied athletes are also blindfolded when playing this sport.
Gameplay in American football consists of a series of downs, individual plays of short duration, outside of which the ball is or is not in play. These can be plays from scrimmage – passes, runs, punts or field goal attempts – or free kicks such as kickoffs and fair catch kicks. Substitutions can be made between downs, which allows for a great deal of specialization as coaches choose the players best suited for each particular situation. During a play, each team should have no more than 11 players on the field, and each of them has specific tasks assigned for that specific play.
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.
A substitute in the sport of cricket is a replacement player that the umpires allow when a player has been injured or become ill, after the nomination of the players at the start of the game. The rules for substitutes appear in Law 24 of the Laws of Cricket.
In the sport of association football, fouls and misconduct are acts committed by players which are deemed by the referee to be unfair and are subsequently penalised. An offence may be a foul, misconduct or both depending on the nature of the offence and the circumstances in which it occurs. Fouls and misconduct are addressed in Law 12 of the Laws of the Game. A foul is an unfair act by a player, deemed by the referee to contravene the game's laws, that interferes with the active play of the match. Fouls are punished by the award of a free kick to the opposing team. A list of specific offences that can be fouls are detailed in Law 12 of the Laws of the Game ; these mostly concern unnecessarily aggressive physical play and the offence of handling the ball. An infringement is classified as a foul when it meets all the following conditions:
- It is committed by a player ;
- It occurs on the field of play;
- It occurs while the ball is in play;
- It is committed against an opponent.
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.
Unsportsmanlike conduct is a foul or offense in many sports that violates the sport's generally accepted rules of sportsmanship and participant conduct. Examples include verbal abuse, taunting of an opponent or a game official, an excessive celebration following a significant play, or feigning injury. The official rules of many sports include a general provision whereby participants or an entire team may be penalized or otherwise sanctioned for unsportsmanlike conduct.
