Substitutes shape the rhythm of a match, letting managers adjust tactics, manage fatigue, and respond to what is happening on the pitch. The rules can vary by competition, though, which is why knowing the basics helps the whole game make more sense.
This guide explains how many changes teams can make, how many players can be named on the bench, and what happens in extra time. It also covers red cards, concussion protocols, the official procedure for making a change, and the most common myths.
By the end, you will be able to follow substitutions with confidence and understand why managers make the choices they do.
How Many Substitutes Are Allowed In A Football Match?
In many competitions, teams can make up to three substitutions during normal time. A growing number of leagues and tournaments now permit five, usually to support player welfare during busy schedules. Wherever five are allowed, most competitions limit teams to three in‑play opportunities to make those changes, with half-time treated separately.
The exact limit is set by each competition, so it is always worth checking the match regulations. Even when five are permitted, teams might not use them all if the flow of the game or their tactical plan does not require it.
So, what does that look like inside the 90 minutes?
How Many Substitutions Are Allowed During Normal Time?
During the 90 minutes, the same overall limits apply as set out above. Where five changes are permitted, competitions usually cap the number of in‑play stoppages a team can use for substitutions at three, which encourages fewer, more decisive windows. Any changes made at half-time do not use up one of those windows.
A typical example is a manager making a double change in the 70th minute, which counts as two substitutions but only one in‑play opportunity. That preserves another window for later without exceeding the total number of changes allowed.

How Many Substitute Players Can Be Named On The Bench?
The size of the bench depends on the competition. Many top-level fixtures allow up to nine named substitutes, while others limit it to seven or even five. Youth and grassroots matches can differ again.
The list matters because it defines a manager’s options. You might see two goalkeepers among the substitutes for knockout ties, or a mix of defenders, midfielders and forwards to keep tactical choices open. Even with a long bench, only the permitted number of players may actually enter the match.
With selection set, what happens if the game goes beyond 90 minutes?
How Do Extra Time Substitutions Work?
When a match goes to extra time, some competitions allow an additional substitution on top of those available during normal time. Where this is in place, a team that has already used the maximum in regular play can still make one more change in extra time. If any changes remain unused from normal time, they carry over.
There are often extra substitution windows at the break before extra time and at half-time in extra time, which sit outside the in‑play limits. As ever, the details are competition specific, so the match rules will spell out exactly what applies.
Discipline can also affect on‑field numbers, which raises a common question.
What Happens To Substitution Limits After A Red Card?
A red card reduces the number of players on the pitch, not the number of substitutions available. Teams cannot replace the dismissed player, and the substitution limit stays the same as it was before the sending off.
Managers often alter their plans, for example, bringing on a defender or extra midfielder at the next opportunity, but they must do so within the original substitution allowance and window limits.
Player welfare has its own set of rules, too.
What Are The Rules For Concussion Substitutes?
Concussion protocols allow an additional, permanent substitution when a player is suspected of having a concussion. This change sits outside the regular limit, so it does not reduce the number of standard substitutions a team can make. To keep things fair, the opposing team is usually granted an extra substitution as well.
The process involves an assessment by medical staff. If a player shows signs of concussion, they are removed from the match and cannot return. The exact framework can vary by competition, but the principle is the same: safety comes first.
That leads to a practical point: when does a change officially count?
What Counts As A Used Substitution?
A substitution is used when the referee gives permission and the substitute actually enters the field to replace a team‑mate. Warming up or standing at the touchline does not count. Changes made at half-time still use up a substitution, they simply do not use one of the in‑play windows mentioned earlier.
If several players are replaced during one stoppage, each counts as a separate substitution, even though they share the same opportunity. The same applies to goalkeepers, whose replacements are treated like any other change under the laws of the game.
Knowing the process helps explain why substitutions can take a moment to complete.
Substitution Procedure And Match Official Signals
Before a change, team staff inform the fourth official, who checks the player details. The substitute waits at the halfway line until the referee authorises the change at a suitable stoppage. The player coming off must leave the field before the replacement steps on, usually at the nearest boundary unless told otherwise.
To make it clear to everyone in the stadium and those watching on television, the fourth official raises an electronic board showing the numbers of the players leaving and entering. Once the new player has crossed the touchline with the referee’s permission, the substitution becomes official.
Even with a standard process, competitions do tweak the details.
Competition Variations On Substitution Rules
Rules can differ from one competition to another. Some allow five substitutes, others stick to three. Bench sizes vary, extra time policies are not identical, and the number of in‑play windows permitted for changes can be different as well.
International tournaments, domestic leagues, cup ties, youth games and grassroots football often set their own parameters. Temporary adjustments may also be introduced to address fixture congestion or player welfare. The headline message is simple: always check the competition regulations for the match you are watching.
With so many variations, it is easy to see how a few myths slip into conversation.
Common Misconceptions About Football Substitutes
- Any named player on the bench can come on at any time. In reality, changes only happen at stoppages and with the referee’s approval.
- A red card can be cancelled out by a substitution. It cannot, the team must continue with fewer players.
- All named substitutes can be used. Only the number allowed by the competition may enter the match.
- Extra time always means an extra substitute. Sometimes it does, sometimes it does not, and it depends entirely on the competition rules.
