Sin Bin and Send Offs in Rugby: Understanding the Discipline System

Rugby, known for its physicality and intensity, places a strong emphasis on sportsmanship and fair play. To maintain order and ensure the safety of players, the game has a well-defined system of disciplinary measures, two of which are the sin bin and send offs. These are critical aspects of rugby that help maintain the integrity of the sport. In this article, we will explore the sin bin and send offs, their purpose, how they are enforced, and their impact on the game.

  1. Understanding the Sin Bin

The sin bin is a key disciplinary tool in rugby, primarily used to penalize players for serious infringements or foul play. It is a temporary suspension, and players spend a specific amount of time off the field as a penalty for their actions. The sin bin is symbolized by a yellow card, which the referee shows to the offending player.

Purpose of the Sin Bin: The primary purpose of the sin bin is to deter players from committing serious offenses and to ensure player safety and fair play. It aims to provide a punishment that is severe enough to discourage foul play but not overly punitive, allowing players to return to the game after serving their time.

Common Offenses Resulting in a Sin Bin: Several offenses can lead to a player being sent to the sin bin, including:

  • Dangerous tackles: High tackles, spear tackles, or tackles that endanger an opponent’s safety.
  • Repeated infringements: When a player accumulates multiple penalties, the referee may issue a yellow card to that player.
  • Professional fouls: Deliberate infringements, such as slowing down the opposition’s ball at the ruck or killing the ball to prevent a try.
  • Deliberate knock-ons: Intentionally knocking the ball forward to disrupt the opposition’s play.

Duration of the Sin Bin: The typical duration for a sin bin punishment is ten minutes. During this time, the offending player’s team plays with one less player on the field, which can significantly impact the team’s ability to defend or attack. The player may return to the game after the ten-minute period has elapsed.

Impact on the Game: The sin bin is an effective deterrent against foul play and provides a balanced response to offenses. While the player serves their punishment, their team must adapt tactically, either by defending with fewer players or by playing more conservatively in attack. The sin bin offers a way to penalize offenders without unduly affecting the balance of the game.

  1. Understanding Send Offs

A send off is a more severe disciplinary measure in rugby and involves the permanent expulsion of a player from the match. Send offs are generally reserved for severe foul play, endangering the safety of others, or repeated serious infringements. A player who is sent off is shown a red card by the referee and cannot return to the game.

Purpose of Send Offs: Send offs are employed to maintain the safety and integrity of the game, ensuring that players who engage in severe misconduct are removed from the match. This punishment is used sparingly and only in cases where there is a clear and significant breach of the rules.

Common Offenses Resulting in Send Offs: Offenses that may result in a player being sent off include:

  • Dangerous play: This can include high tackles that make contact with the head or neck area, striking an opponent, eye gouging, or other deliberate acts of violence.
  • Serious foul play: Actions such as stamping on an opponent, kicking, or elbowing an opponent can lead to a red card.
  • Repeated misconduct: A player may be sent off if they have received a yellow card (sin bin) and continue to commit offenses.
  • Citing: After the match, a citing commissioner reviews video footage and reports incidents of potential foul play to the disciplinary committee. If found guilty, a player can receive a suspension, which may be equivalent to a send off.

Impact on the Game: A send off is a significant event in a rugby match. The team of the player who has been sent off is reduced to 14 players for the remainder of the game. The imbalance can lead to tactical adjustments, and the team must adapt to the loss of a player. In some cases, a send off can profoundly influence the outcome of a match, particularly if it occurs early in the game.

  1. Referee’s Decision-Making Process

The decision to issue a yellow card (sin bin) or a red card (send off) rests with the match referee. Referees are responsible for interpreting the laws of the game and ensuring player safety and fair play. When deciding whether to issue a card, referees consider several factors:

  • Severity of the offense: Referees evaluate the nature and seriousness of the foul play or infringement. Actions that pose a high risk of injury are more likely to result in a card.
  • Intent: Whether the player’s actions were accidental or deliberate is taken into account. Deliberate actions are more likely to lead to a card.
  • Repeated offenses: Referees may issue a card for repeated or persistent infringements by a player or team.
  • Player’s previous conduct: A player’s previous disciplinary record, especially during the match in question, can influence the referee’s decision.

Video Review and TMO: In some cases, referees may consult the Television Match Official (TMO) for assistance in making card-related decisions. The TMO reviews video footage to provide the referee with additional information and ensure accurate decision-making.

The role of the TMO is particularly relevant for incidents that may have been missed or not fully observed by the referee during live play. This additional level of scrutiny contributes to a fair and thorough assessment of disciplinary incidents.

  1. The Impact on Teams and Strategies

Both the sin bin and send offs have significant consequences for teams and their playing strategies.

  • Sin Bin: When a player receives a yellow card and is sent to the sin bin, their team plays with one fewer player for ten minutes. This period can create tactical challenges, and teams must adapt their strategies accordingly. For example, in defense, they may opt for a more conservative approach or shift to a strategy that prioritizes ball retention.
  • Send Offs: A red card, which results in a player’s expulsion from the match, is a more severe penalty. The team plays with 14 players for the remainder of the game. This imbalance can have a profound impact, potentially altering the outcome of the match. Teams often reorganize their strategies, focusing on minimizing the impact of the loss of a player and maintaining a strong defensive structure.
  1. The Disciplinary Process After the Match

The disciplinary process in rugby extends beyond the match itself. Incidents that result in a card, particularly those involving send offs or serious foul play, are subject to post-match review and potential sanctions.

  • Citing Commissioner: A citing commissioner reviews video footage and reports on any incidents that warrant further examination. They can cite a player for potential foul play or breaches of the laws of the game.
  • Disciplinary Committee: If a player is cited, a disciplinary committee is convened to assess the incident. The committee reviews evidence, including video footage, and considers the circumstances surrounding the offense. Based on their findings, they may impose sanctions such as suspensions, which can result in the player’s absence from future matches.


The sin bin and send offs in rugby play a crucial role in maintaining the integrity of the sport and ensuring player safety. These disciplinary measures are essential tools for referees to penalize players who engage in foul play or repeatedly infringe the rules. The sin bin provides a temporary suspension, while a send off results in a player’s permanent expulsion from the match. The decision to issue a card is made by the match referee, who evaluates the severity of the offense, the player’s intent, and other relevant factors.

While the sin bin can influence the tactical aspects of a match by reducing a team’s playing strength temporarily, a send off has a more profound and long-lasting impact. The disciplinary process doesn’t end with the match; post-match review by citing commissioners and disciplinary committees ensures that players who commit serious offenses face appropriate sanctions.

Ultimately, the sin bin and send offs contribute to the maintenance of rugby’s core values of sportsmanship, fair play, and respect for opponents. They serve as a reminder that while rugby is a physical and competitive sport, it is equally grounded in principles of integrity and safety.
