Football Substitution Rules Explained: 10-Second Exit Rule

Football substitution rules explained simply: top-level teams get five substitutes, used in no more than three windows plus half-time, and a player coming off has 10 seconds to leave. Miss that and the substitute waits for the first stoppage after one minute. A substituted player can’t return at senior level.

That word “top-level” carries a lot of weight. Friendlies, lower leagues, US college soccer and high school games all run different numbers. The mistake I see most is fans and coaches assuming one competition’s rules apply in another.

What follows: the limits by competition, the new 10-second exit clock, how concussion changes sit outside the count, and the German cup tie that was overturned because a club lost track of its own substitutions.

Key Takeaways

• Count windows as well as players: two changes made in the same stoppage use one window, and half-time doesn’t use one at all.
• The 10-second exit clock came into the Laws for 2026/27; overrun it and your team plays a man short for at least a minute.
• A concussion change sits outside the normal five, but it hands the opponent an extra sub of their own.
• Rules don’t travel between competitions: friendlies, NCAA, high school and grassroots football all use different limits.
• Who pays for a miscount depends on who made it. The DFB took a cup win off Wolfsburg in 2021 but let Bayern’s league win stand in 2022.

How Many Substitutes Can a Team Use?

Five is the ceiling in top-level competitions, and the team sheet can name anywhere from 3 to 15 substitutes. Most of the confusion starts with the windows.

Under IFAB Law 3.2, top-level competitions allow up to five substitutes, used in no more than three substitution opportunities plus half-time. Several changes made during the same stoppage count as one opportunity. Changes made between full time and extra time, or at the extra-time interval, don’t count. Other matches without an agreed number default to six substitutes.

The IFAB Law 3 text is where every competition starts. Each one then adds its own regulations on top. That’s why the same weekend can give you a league match with five subs and an international friendly with eight.

Those friendlies changed this season. For senior ‘A’ international friendlies, the 2026/27 Laws raised the limit to eight, or eleven if both teams agree and tell the referee in advance. The three-window restriction still applies. Concacaf describes it as a rise from six to eight.

Three Windows, Not Five Trips to the Touchline

Windows are where managers get caught out. Bring two players on in the same stoppage and you’ve used one window with three subs left. Spend your windows one at a time, one player each, and you’ll finish with two fit players on the bench and no way to use them.

That’s a manager’s own goal.

Why cap windows at all? IFAB’s 2022 announcement just says the three-slots-plus-half-time restriction was confirmed. My reading is that it stops a team breaking the game into five separate stoppages. That’s my interpretation, though, and the release doesn’t spell out the reasoning.

Extra Time Carries Your Unused Subs Over

Unused substitutes and windows roll straight into extra time. Changes made in the break before extra time, or at its half-time, don’t use a window either.

I think this is one reason extra time is fairer than its critics claim. A manager who held his nerve and kept a change in his pocket gets rewarded for it. The one who emptied the bench at 70 minutes lives with that choice.

The 10-Second Exit Rule That Started on 1 July 2026

The board goes up on the far side of the pitch. The player coming off, a goal up and in no hurry, starts a slow stroll toward his own bench while the away end whistles.

That walk now runs on a clock. Under the 2026/27 Laws, a player being substituted has 10 seconds to leave from the moment the board is shown, at the nearest point on the boundary line. The referee can allow an exit at the halfway line or somewhere else for safety, security or injury. The Irish FA’s guidance to referees starts the clock from the board being displayed or the referee signalling the change.

Count ten out loud from the far touchline next time you’re at a match. It goes quicker than you’d think. A jog across to the halfway line won’t fit inside it, which is the whole point.

Go over the limit and the player still has to leave as fast as possible. He isn’t booked unless he excessively delays the restart. Play restarts, and the substitute can only come on with the referee’s permission at the first stoppage after one minute has passed.

Here’s why that hurts. The team plays a player short for that minute, because the man coming off has already gone and his replacement isn’t allowed on yet. Eleven against ten, by your own doing.

The sources word the timing slightly differently, so here’s each one side by side:

Source	When the substitute can enter after an overrun
IFAB Law 3	First stoppage after one minute has elapsed following the restart
IFAB 2026/27 changes document	First stoppage after one minute has elapsed
Concacaf	First stoppage at least one minute after play has restarted

On the pitch I’d expect these to land in the same place. I can’t promise every referee reads them identically on a wet night, so I’d go with the wording in the 2026/27 Law changes document, since IFAB writes the Laws. Rollout dates vary too. Concacaf says the rules took effect on 1 July 2026 and applied to all its competitions from 20 July 2026.

A slow exit used to end up as stoppage time tacked onto the half. Now the dawdling team pays in players instead. The same season also brought a related rule: a player treated on the field, or who causes play to stop through injury, has to leave and stay off for one minute after the restart, barring certain exceptions.

Football Substitution Rules Explained Step by Step

Five things happen, in this order, every time a change is made. Skip one and the referee has a decision to make.

1. Name your substitutes before kickoff. Law 3 requires the names to be given to the referee before the match starts. Skip this and that person can’t play, even if they’re listed as a team official and want to switch roles at half-time.
2. Tell a match official and wait for a stoppage. Changes happen when the ball is dead. A player who swaps shirts with the goalkeeper mid-play without telling the referee gets booked, and so does the keeper, the next time the ball goes out.
3. Get the departing player off within 10 seconds. Nearest boundary point, unless the referee says otherwise. Overrun it and you’re playing a man down for at least a minute.
4. Wait for the referee’s permission to enter.
5. Treat the substitute as a player only once they’re on the grass. The change is finished at that point. Before it, the team can still swap which substitute it sends on. After it, the new player can take any restart, including a penalty awarded in that same stoppage.

Step five is the one that surprises fans. Because the substitution isn’t complete until the substitute enters, a coach who planned to bring on a forward can switch to a defender if a centre-back goes down while the forward waits at halfway.

One more detail: if the captain comes off, another player on the field has to take the armband. A team always needs a captain the referee can pick out.

The board is the usual cue at big grounds, with the outgoing and incoming numbers lit up and held high so both benches can read them. Lower down the pyramid there’s no board at all, and how officials signal substitutions changes accordingly. That’s why the Irish FA counts the referee’s own signal as starting the clock.

A friend who used to call football dull started coming to weekend games with me. Within about two months he was spotting offside traps before I did. I’d point him at the bench next, because the changes tell you what a manager fears before the shape does.

From a COVID Stopgap to the Permanent Five

The IFAB first allowed five substitutes in May 2020, as a temporary amendment requested by FIFA when the pandemic crammed seasons together. It was extended several times.

The permanent decision came on 13 June 2022 and took effect on 1 July 2022. That same change raised the named-substitute cap from 12 to 15. So the current shape of the bench is barely four seasons old.

Go back far enough and there were no substitutes at all. An injury meant playing on short. That backstory deserves its own page, and I’d rather not throw dates at you from memory here.

Why do managers make changes? The reasons haven’t changed much, even if the numbers have:

• Tactics. A new shape, a fresh press, a different kind of striker to stretch a tired back line.
• Tired legs.
• Injury, including a suspected concussion, which now has its own separate route.
• Protecting a booked player before a second yellow arrives. I think this one is badly underrated. Take off a centre-back on a caution at the right moment and you’ve saved a match nobody will remember you saving.
• Running down the clock. The 10-second rule makes that a lot riskier than it was.

Does five subs favour clubs with deeper squads? It’s the obvious argument, and by eye I find it persuasive. I’ll be straight with you, though: I haven’t seen data that settles it, and numbers aren’t my strong suit. Treat anyone who sounds certain either way with some care.

What I will say is this. A bench works like good joinery. Five quality subs who don’t fit the shape you’ve built are a stack of fine timber with no plan for the joints.

Concussion Substitutes Sit Outside the Normal Count

A concussion change doesn’t touch a team’s five. IFAB approved additional permanent concussion substitutions at its 138th AGM on 2 March 2024, and each competition chooses whether to use them.

Permanent concussion substitutes are for an actual or suspected concussion. The player who comes off takes no further part in the match. Here’s how the protocol works:

• The change can be made regardless of how many substitutes the team has already used.
• The team tells the referee or fourth official, ideally with a substitution card of a different colour.
• The opponent gets an additional substitute and an additional window. That extra window works only for the extra substitute.
• A normal change made at the same time as a concussion change still counts as one of the normal windows.
• Once a team’s normal windows are gone, it can’t dress up a tactical change as a concussion change.
• Each team gets one per match, and the concussed player sits out any penalty shoot-out too.

The design closes its own loopholes. The opponent’s bonus window is tied to its bonus substitute, so it can’t be banked for a normal change later. And the team making the concussion change can’t sneak a tactical swap through the same door once its windows run out.

A concussion substitution is a one-way door. The player is done for the day, shoot-out included, and the other bench gets a bonus change.

Not everyone likes the “permanent” part. FIFPRO and the leagues pushed for temporary concussion substitutes, so a player could be assessed off the pitch and then come back. I’m no doctor, so I won’t pretend to settle the medical side of that argument.

Can a Substituted Player Come Back On?

At senior level, no.

Once a player is off, they’re done. IFAB allows return substitutions only in youth, veterans, disability and grassroots football, and only with the agreement of the national association, the confederation or FIFA. A replaced goalkeeper follows the same rule.

This is where the “rules travel” mistake does the most damage. Here’s how the main levels compare:

Level	Substitute limit	Windows	Re-entry
IFAB top-level competitions	5 (3 to 15 named)	3, plus half-time	No
Senior ‘A’ international friendlies	8, or 11 by agreement	3	No
Other matches, no agreed number	6	Competition rules	No
NCAA Division I men’s	Set by NCAA rules	6, plus 1 in overtime	None in either half
NCAA women’s and other divisions	Set by NCAA rules	Set stoppages only	One in the second half
Youth, veterans, disability, grassroots	Competition rules	Competition rules	Allowed with approval

I’ll be honest: the American college and high school game sits outside what I know best. I’m leaning on the rulebooks here more than my own eyes.

From 2024, the NCAA men’s soccer substitution rules for Division I stopped re-entry in both halves and capped teams at six windows a game, plus one in overtime. Women’s soccer and the other divisions kept one second-half re-entry.

High school runs its own scheme again. The NFHS 2025-26 soccer rules changes let teams substitute during temporary stoppages such as water breaks. They also require a player to come off if the referee waves a coach or medic on to check them, goalkeepers included.

Picture a fan raised on NCAA women’s games who expects a second-half return. Take them to a senior league match and they’ll wait all afternoon for it.

What Happens When a Substitution Goes Wrong?

What happens when a club simply loses count? Before the big cases, here are the smaller ones the Laws already answer:

Situation	Ruling under IFAB Law 3
Player refuses to come off	Play continues
Named sub starts in place of a named player, referee not told	No sanction; count not reduced; reported
Outfield player swaps with keeper mid-play, referee not told	Both booked when ball next goes out
Same swap at half-time, spotted later	No cards; reported to authorities
Sub requested but not made before extra time ends	Can’t be made before penalties
Substitute enters the video operation room	Red card; not replaced; count not reduced

Most of the strange cases involve goalkeeper substitution rules, because a keeper change needs the referee told first and has to happen during a stoppage. A team can bring on a substitute keeper for a penalty if it still has subs and windows left. If the keeper gets hurt and the team has nothing left, an outfield player goes in goal wearing a shirt that clearly marks them out.

The Player Who Won’t Come Off

Law 3’s answer is short: if a player refuses to be substituted, play continues. That’s it. The Laws don’t attach a specific punishment to the refusal in that answer, and I’d love to see a referee’s report on the next one.

Walking off is a different matter. An additional change approved on 28 April 2026 says a match can’t start or continue if either team has fewer than seven players. A team responsible for that is, in principle, forfeited, subject to competition regulations.

Where this goes sideways: A substituted player walks along the touchline, sees an attack coming and steps back on to stop it. That’s two yellows on the spot, one for re-entering and one for stopping a promising attack, then a red and a direct free kick.

Two DFB Cases, Two Opposite Verdicts

The cleanest lesson in miscounting comes from Germany. On 8 August 2021, in the DFB-Pokal at Preussen Muenster, Wolfsburg used a sixth substitute in extra time. Neither the officials nor the club noticed.

The DFB tribunal replaced Wolfsburg’s 3-1 win with a 2-0 win for Muenster. The tribunal said keeping track of substitutions is the club’s job.

Eight months later the same body went the other way. On 2 April 2022 at Freiburg, the fourth official’s board showed the wrong number, so a Bayern player stayed on. Bayern had 12 players for about 17 seconds, according to a secondary report of the ruling. Freiburg appealed, and the DFB rejected it because the officials were at fault. Bayern’s 4-1 win stood.

So which is it, club or officials? Both, depending on who made the error.

If I were on a coaching staff, I’d keep my own written tally of subs and windows and check it against the fourth official at every change. The Wolfsburg ruling says the club owns that count, and the board won’t save you.

Frequently Asked Questions

Can a player refuse to be substituted?

Yes, in the sense that the referee won’t drag them off. IFAB’s Law 3 guidance says that if a player refuses to be substituted, play simply continues. Any consequences after that sit with the club and the competition.

Why did substitutions go from three to five?

Five subs began in May 2020 as a temporary COVID-era measure that FIFA requested. After several extensions, IFAB made it permanent on 13 June 2022, effective from 1 July 2022. The three-window restriction plus half-time stayed in place.

Can a team make six substitutions?

In some matches, yes. If teams don’t agree a number before a match outside top-level competition, the limit is six. Senior ‘A’ international friendlies now allow eight, or eleven if both teams agree and tell the referee in advance.

Can a substitute take a penalty straight away?

Yes. A team with subs and windows left can make a change during the stoppage for a penalty. Once the substitute steps onto the field they become a player and can take the kick.

What if a substitution is requested but not made before extra time ends?

It can’t be made before the shoot-out. Only players on the field, or temporarily off it, at the final whistle can take part in penalties. The one exception is replacing a goalkeeper who can’t continue.

Before You Go

Here’s the one thing to do before your next match: check which competition you’re watching and look up its own limit. Five, six, eight, eleven or six windows in US college soccer are all live numbers right now, depending on who’s playing and where.

Then watch the windows, not just the bodies. Once a manager has used all three, the bench is shut for normal changes, no matter how many fit players are sitting on it. Only a concussion change opens a fresh door at that point.

My lens is European, and the American game in particular runs on rules I know from the page rather than the stands. If that’s your game, trust the NCAA and NFHS rulebooks over anything you’ve picked up watching Saturday league football. Football substitution rules explained from one level rarely survive the trip to another.
