A football match cannot start or continue with fewer than seven players.

How officials handle the player count

1. Before kick-off, confirm each team has at least seven eligible players and one player acting as goalkeeper.
2. If a team starts with fewer than eleven, check the team list and competition rules for late-arriving players and substitutes.
3. During the match, track players who are sent off, injured, substituted, temporarily off the field, or have deliberately left.
4. If a team is definitely below seven eligible players, the match cannot start or continue.
5. If the ball is in play and the shortage was caused by players deliberately leaving, decide whether advantage can be played before the next stoppage.
6. Report the facts. The competition organiser, not the referee alone, normally decides the final administrative consequence of an abandoned match.

The minimum is seven players per team

Under the standard Laws of the Game, football is played by two teams with a maximum of eleven players each, and one player on each team must be the goalkeeper. A match may not start or continue if either team has fewer than seven players.

This is a team-by-team minimum. It is not enough that there are fourteen players on the field in total; each side must have at least seven of its own eligible players. If one team falls below the minimum, the problem belongs to that team even if the other side still has a full eleven.

A team does not need eleven to kick off

A team can start a standard match with seven, eight, nine, or ten players if the competition allows the match to proceed and the players are properly eligible. The Laws set the minimum, not a requirement that every team must have eleven at kick-off.

If competition rules require players and substitutes to be named before kick-off, late arrivals can only take part if they were named on the team list. A team cannot simply add an unlisted player later because it started short.

One player must be the goalkeeper

Each team must have a goalkeeper. If a goalkeeper is sent off, injured, or substituted, another eligible player must take that role before play continues. That player can be a substitute if the team still has a substitution available, or an outfield player changing places with the goalkeeper under the usual procedure.

The goalkeeper requirement is separate from the seven-player minimum. A team with seven players still needs one of those players to be clearly acting as goalkeeper.

Send-offs can take a team below the limit

A sent-off player cannot be replaced. In an 11-a-side match, a team that receives one red card plays with ten, two red cards leaves it with nine, and so on. If send-offs reduce the team to fewer than seven players, the match cannot continue.

This is why five send-offs for one team in a full-strength 11-a-side match usually creates the minimum-player problem: eleven minus five leaves six. The referee still reports the send-offs and the abandonment, while the competition rules decide what happens to the result.

Injuries can create the same problem

The rule is not only about red cards. If injuries, unavailable substitutes, or a combination of injuries and send-offs leave a team unable to field seven eligible players, the match cannot continue under the standard law.

A player receiving treatment, correcting equipment, or temporarily off the field does not automatically mean the match is abandoned at that instant. The practical question is whether the team can legally continue or restart with at least seven eligible players when required.

Leaving the field does not always stop play instantly

Law 3 has a specific safeguard for players who deliberately leave the field and take their team below seven while the ball is in play. The referee is not obliged to stop immediately, and advantage may be played if that is fair for the opponents.

That advantage is temporary. Once the ball next goes out of play, the match must not resume if the team still does not have the minimum seven players. This prevents a team from killing an attack by walking off while the ball is live, but it does not let the match continue indefinitely below the minimum.

What an abandoned match means

An abandoned match is a match the referee stops before it is completed and does not restart. Falling below the seven-player minimum is one reason this can happen, but matches can also be abandoned for severe weather, unsafe field conditions, floodlight failure, crowd disorder, outside interference, serious injury situations, or other conditions that make play unsafe or impossible.

The referee's role is to decide whether the match can safely and legally continue, then report the relevant facts. The referee does not usually decide the league-table result, replay date, forfeit score, disciplinary consequences, or whether the score at abandonment stands.

The result is not automatic everywhere

The Laws say an abandoned match is replayed unless the competition rules or organisers determine otherwise. That wording matters. Some competitions may order a replay, some may award a forfeit, some may let a result stand in defined circumstances, and some may impose additional disciplinary sanctions.

For a neutral rules explanation, avoid assuming a universal scoreline such as 3-0. The match law explains when play cannot continue; the competition regulations explain the administrative outcome.

Youth and local formats can use different numbers

The seven-player minimum belongs to standard 11-a-side football under the Laws of the Game. Youth, grassroots, veterans, disability, small-sided, futsal-style, and local formats may use modified player numbers and minimums under their own competition rules.

When a match is not ordinary 11-a-side football, the first check is the competition's format: how many players start, how many may be on the field, how substitutions work, and what minimum number is required to continue.

Misunderstandings to avoid

• "A match must start with eleven" is wrong under the standard law. Seven is the minimum, although competition rules and team-list requirements still matter.
• "The referee can just play on with six" is wrong once the team is below the minimum and play must start or restart.
• "Five red cards always means a 3-0 loss" is too broad. The match cannot continue below seven, but the competition decides the administrative result.
• "If players walk off, the whistle must go immediately" is too simple. If the ball is in play, the referee may allow advantage before the next stoppage.
• "Temporary treatment always reduces the official team count" is too broad. Officials look at whether the team can legally continue or restart with enough eligible players.
