Sin Bins in Football Explained: How Temporary Dismissals Work Under the Laws of the Game

A sin bin, or temporary dismissal, is a punishment in which a player who commits a cautionable offence must leave the field for a set period before returning. It is written into the Laws of the Game as an option for certain levels of football, and for readers following discipline data on RubiScore, it is a reminder that a yellow card does not carry the same weight in every competition.

Card and discipline records at https://rubiscore.com cover professional competitions, where the standard system of yellow and red cards applies. Sin bins work differently. This explainer covers where they are allowed, how the two official systems operate, what happens in unusual situations, and why the idea keeps returning to debates about the professional game.

Where Are Sin Bins Allowed?

The International Football Association Board (IFAB), which writes the Laws of the Game, added temporary dismissals to the Laws in 2017. Under the current guidelines, sin bins for some or all cautionable offences are an option in youth, veterans, disability and grassroots football. Each competition needs approval from the relevant national football association, confederation or FIFA.

The IFAB's 138th Annual General Meeting approved a revised version of the guidelines, and the current Laws still limit sin bins to those levels of the game. Top professional leagues and international competitions continue to use the standard system, in which a caution carries no immediate time penalty.

In England, the Football Association adopted sin bins for grassroots football and chose to apply them to a single offence: dissent.

How Does a Temporary Dismissal Work?

The IFAB guidelines set out a detailed procedure:

  • The signal. The referee shows a yellow card and then points with both arms toward the temporary dismissal area, usually the player's technical area.
  • The length. The period is the same for every offence and should be between 10 and 15 percent of the total playing time: for example, 10 minutes in a 90-minute match or 8 minutes in an 80-minute match.
  • The start. The clock starts when play restarts after the player has left the field.
  • Stoppages. Time lost to stoppages that would normally be added at the end of the half is also added to the dismissal period, so the player misses the full amount of playing time.
  • The return. Once the period ends, the player can come back from the touchline with the referee's permission when the ball is next out of play.
  • Substitution. A temporarily dismissed player can only be substituted after the period has finished, and only if the team still has substitutions available.
  • Where the player waits. The player stays in the technical area, or with the coaching staff, and may warm up under the same conditions as a substitute.

The rules also cover the edges of the match. If a period is unfinished at half-time, the rest is served at the start of the second half, and the same applies going into extra time. A player still serving a temporary dismissal at the end of the match may take part in a penalty shoot-out, because sin bins do not apply during shoot-outs.

Temporary dismissals apply to all players, including goalkeepers, but not to cautionable offences committed by a substitute or a player who has already been substituted.

What Are System A and System B?

Competitions choose between two systems.

System A: every caution

Under System A, every cautionable offence is punished with a temporary dismissal. A player who receives a second caution in the same match serves a second temporary dismissal and then takes no further part. Because the team has already played short-handed for two periods, the player may be replaced by a substitute at the end of the second period, if the team has substitutions left.

System B: selected cautions

Under System B, only a predefined list of cautionable offences leads to a temporary dismissal. All other cautions are ordinary yellow cards. A player who receives two cautions in the same match is sent off in the usual way, even if one or both of those cautions was a sin-bin offence.

The IFAB suggests that competitions using System B may want to focus on behaviour-related offences, such as:

  • Dissent by word or action, including gestures.
  • Simulation.
  • Delaying the opposing team's restart.
  • Stopping a promising attack by holding, pulling, pushing or deliberate handball.
  • Illegal feinting by a kicker at a penalty kick.

What If a Player Offends While in the Sin Bin?

A temporarily dismissed player who commits another cautionable offence, or a sending-off offence, during the dismissal period takes no further part in the match and cannot be replaced. The rule prevents a player from using the time off the field to cause further trouble without consequence.

Competitions also decide whether temporary dismissals must be reported and whether further sanctions follow, such as a suspension after a set number of temporary dismissals, in the same way that accumulated yellow cards can lead to a ban.

Why Were Sin Bins Introduced?

The IFAB describes the philosophy as instant punishment. A yellow card in the standard system has no immediate effect on the match, while a temporary dismissal costs the offending team a player straight away. The intention is that this has a strong and immediate effect on the behaviour of the player and, potentially, the whole team.

Dissent is the clearest target. Arguing with officials is a persistent problem at grassroots level, where referees often work alone, and a punishment that changes the match immediately is seen as a stronger deterrent than a card with no on-field effect.

How Does a Sin Bin Change a Match?

A temporary dismissal creates a short spell of numerical disadvantage. In a 90-minute match, a 10-minute period is roughly one ninth of the game, compared with a red card, which removes a player for the rest of the match.

The effect depends on timing. A dismissal shortly before half-time is split across the interval, giving the short-handed team a chance to reorganise. A dismissal in the closing minutes can leave a team defending a lead with ten players at the most dangerous point of the match. Teams usually respond as they would to a red card, by dropping a forward or a midfielder to keep the defensive shape intact, but only for a limited time.

A Worked Example

Imagine a hypothetical grassroots match played under System B, with sin bins for dissent only. In the 40th minute, a midfielder argues with the referee and is temporarily dismissed for 10 minutes. Play restarts, the half ends a few minutes later, and the rest of the period is served at the start of the second half.

In the 70th minute, the same player commits a reckless tackle. That is a caution but not a sin-bin offence under this competition's list, so the referee shows an ordinary yellow card. Because it is the player's second caution of the match, the player is sent off, even though the first caution was punished with a temporary dismissal. Under System A, the same sequence would instead lead to a second ten-minute period, after which the player would take no further part but could be replaced.

Sin Bins Compared With Yellow and Red Cards

The three sanctions sit on a scale:

  • Standard yellow card. No immediate effect on numbers. Counts toward a second-caution dismissal and, in many competitions, toward suspension totals.
  • Temporary dismissal. The team plays a player short for a fixed period, then returns to full strength.
  • Red card. The team plays a player short for the rest of the match, and further suspension usually follows.

Football is not the only sport to use the idea. Rugby union has long used a sin bin for yellow cards, and ice hockey's penalty box works on a similar principle. Football's version is distinctive because it remains an option for specific levels of the game rather than a universal rule.

Why Have Sin Bins Not Reached the Elite Game?

Extending sin bins to professional football raises practical questions. Accurate timing of the dismissal period, how tactical fouls should be treated, and how the change would interact with suspensions and existing disciplinary systems would all need settling. So far, the Laws keep temporary dismissals as a tool for youth, veterans, disability and grassroots competitions, while other measures aimed at improving behaviour toward officials have been introduced for the professional game.

How Should Discipline Data Be Read Where Sin Bins Exist?

Card counts from a sin-bin competition and from a standard competition measure different things. A yellow card under System A or System B may have cost the team ten minutes with a player short, while a yellow card in the professional game had no immediate cost. In the professional competitions covered on RubiScore, every caution follows the standard system, so card totals from those leagues and from sin-bin competitions should not be compared directly. Where sin-bin records exist, the useful details are which system applied, which offence triggered the dismissal, and how many minutes the team spent short-handed.
