Local Adaptations of FIFA Rules
The 2025/26 Laws of the Game keep football consistent worldwide, but they also allow national associations some flexibility to adapt the rules for different levels of play. These adjustments make sure the sport remains fair while also meeting the needs of youth players, veterans, disability football, and grassroots competitions.
At all levels, associations can permit up to five substitutes per team, introduce permanent concussion substitutions to protect player welfare, and apply the “only the captain” guideline to improve communication with referees. For youth, veterans, disability, and grassroots football, there is even more room to adapt. Organizers can change the size of the field, goals, and ball, shorten match duration, adjust player numbers, and allow return substitutes so players can rejoin after being taken off. Temporary dismissals, or “sin bins,” can also be used for certain offences, and captains must wear a compulsory armband to make their role clear.
National associations decide age limits for youth and veterans football and define what counts as grassroots competitions. However, IFAB insists that the way the game is refereed must remain consistent everywhere, from the World Cup to a local match. No other changes are allowed unless IFAB gives permission, often through official trials like cooling‑off periods after mass confrontations. Associations are also asked to report back when they use modifications, so IFAB can learn from their experiences and share good practices globally.
Temporary Dismissals (“Sin Bins”) and Return Substitutes
Temporary dismissals, often called “sin bins,” are designed as an instant punishment for certain offences. They are mainly used in youth, veterans, disability, and grassroots football, where behavior management is especially important. Removing a player for a short period can quickly improve their behavior and remind the team of the importance of respect.
Organizers can choose how to apply sin bins. In one system, every yellow card offence leads to a dismissal period. In another, only specific offences such as dissent, simulation, or deliberately delaying play result in a sin bin, while other cautions remain standard yellow cards. The dismissal lasts about 10 minutes in a 90‑minute match, and the referee signals it by showing a yellow card and pointing to the dismissal area. Players may return only with the referee’s permission when the ball is out of play. If a player misbehaves again while serving a dismissal, they are excluded permanently and cannot be replaced.
Return substitutes are another modification allowed in 2025/26. This rule lets a player who has already been substituted come back into the match later, replacing another teammate. It is not used in professional competitions but is permitted in youth, veterans, disability, and grassroots football, where participation and enjoyment are the main goals. It ensures more players get meaningful game time, reduces the physical strain for older or disabled players, and supports development at youth level.
Concussion Substitutions
The 2025/26 Laws also include a special rule for concussion substitutions, designed to put player safety first. This modification applies at all levels of football and was formally approved in 2024. It allows teams to take a player off the field if they suffer a suspected or confirmed concussion, without being left at a disadvantage.
Each team is allowed one concussion substitution per match, and this can be used even if they have already made all their normal changes. In some competitions, a previously substituted player can even return to the field as the concussion replacement. To keep things fair, whenever one team uses a concussion substitution, the other team automatically gets the option to make an extra substitution of their own for any reason.
The process is straightforward. The referee or fourth official must be notified, often with a special colored card or form. The substitution can happen immediately after the injury, after an assessment, or later if symptoms appear after the player has gone back on the field. Once replaced, the player cannot return to the match or take part in a penalty shoot‑out, and they should be taken to a medical facility if possible.
Referees are not responsible for diagnosing concussions, but they play a supportive role. They can delay the restart of play to ensure the injured player leaves safely, and they must report if they suspect the rule is being misused for tactical reasons. This ensures the integrity of the game while keeping player welfare the top priority.
Together, these modifications—general adjustments, sin bins, return substitutes, and concussion protocols—show how football balances universality with flexibility. The Laws remain consistent across the world, but they also adapt to protect players, encourage participation, and improve behavior. By combining fairness, safety, and respect, the 2025/26 Laws of the Game ensure football continues to be enjoyed at every level, from grassroots matches to the highest competitions.
