The One-Minute Gap

A substitution board goes up. The player leaving the pitch makes his way towards the touchline, while his replacement waits to come on.

It is one of the most familiar moments in football. A manager wants fresh legs, a different attacking option or more protection for the final minutes.

Normally, attention goes straight to the new player.

But under the 2026/27 rules, what happens before that player enters the pitch could matter just as much.

The departing player now has a ten-second deadline. If he takes too long without an accepted reason, the substitute cannot come on immediately. The match restarts, and the team has to continue with one fewer player until the replacement is allowed to enter.

There is no red card. The manager may even have made a perfectly reasonable substitution.

Yet the team suddenly faces a different problem from the one the change was supposed to solve.

A separate goalkeeper-injury trial in participating English competitions creates another situation in which a team can temporarily lose an outfield player.

Both measures are intended to discourage unnecessary delays. For coaches, however, they introduce a practical question that cannot be answered by reading the team sheet.

If one player is unavailable for the next minute, what should the remaining ten protect?

When ten seconds becomes more than ten seconds

The International Football Association Board (IFAB) has introduced a time limit for players being substituted.

Normally, the player leaving must be off the pitch within ten seconds of the substitution board being shown. If no board is used, the referee’s signal starts the countdown.

The player should leave at the nearest boundary unless the referee directs otherwise. Where the substitute needs an equipment check, the countdown begins only after that process is completed and the substitution is signalled.

There are sensible exceptions. A genuine injury may prevent a player from leaving quickly, while safety or security concerns may make the nearest exit inappropriate. The protocol also allows the replacement to enter if the departing player is already very close to leaving when the countdown expires.

But if the time limit is exceeded without an applicable exception, the change must still go ahead.

The departing player leaves. The manager cannot cancel the substitution or choose a different replacement.

The substitute must wait until the first stoppage after at least one minute has elapsed following the restart.

That last detail is important.

It does not mean the substitute automatically enters exactly sixty seconds later. If the ball remains in play, the team continues short-handed until the next stoppage, when the referee can permit the replacement to enter.

A yellow card is not automatic either. The protocol reserves a caution for excessive delay.

So the immediate consequence may be more significant than a booking: a team that expected to refresh its eleven players must instead manage a spell with only ten.

The substitution was supposed to protect a lead

Consider a hypothetical match.

A team leads 1–0 with ten minutes remaining. Its manager decides to replace a tiring winger with a fresher player who can help defend the flank and offer an outlet on the counterattack.

It makes sense. The manager wants to protect the lead without giving up every possibility of attacking.

But suppose the departing winger exceeds the ten-second limit, with no applicable exception, and the replacement is delayed.

The plan changes immediately.

Instead of gaining fresh support out wide, the team now has nine outfield players and a goalkeeper. The opponent still has its full eleven.

The manager has to decide what matters most during that temporary disadvantage.

One option would be to keep the remaining midfielders closer to the defence and avoid sending too many players into the first wave of pressure. That could make it harder for the opposition to find space directly in front of the centre-backs.

At the same time, somebody still needs to offer a route forward when possession is recovered. Otherwise, every clearance risks giving the ball straight back.

The adjustment comes with a price.

If the team presses less aggressively, the opponent may have more time to move the ball across the pitch and deliver crosses. If everyone retreats too deeply, the defending side could end up facing attack after attack.

There is no reason to assume that dropping ten yards automatically solves the problem.

Now imagine the same delay with the team losing 0–1.

The manager cannot afford to abandon every attacking option simply to keep a compact defence. The team still needs an equaliser.

A more selective press might be useful: hold the central positions when the opponent has easy passing options, then close down together when the ball reaches the touchline and the receiver has fewer ways out.

But this creates another trade-off. The opponent may retain possession for longer, while the attacking team has fewer chances to win the ball close to goal.

Neither approach is a guaranteed solution.

The useful lesson is that the same delayed substitution can require two different responses, depending on the score and the position of the missing player.

The original substitution might have been correct. Its delayed execution creates a new decision that the coach must manage.

The goalkeeper creates a different problem

The goalkeeper-injury trial reaches a similar issue from another direction.

An outfield player who receives treatment may have to leave the pitch temporarily. A goalkeeper cannot be treated in exactly the same way, because a team must maintain a goalkeeper on the field.

That distinction is necessary for safety and for the game to function.

It also creates an opportunity for goalkeeper-injury stoppages to interrupt the match for longer than an ordinary outfield treatment break.

For 2026/27, participating English competitions have adopted an IFAB-approved trial designed to discourage the tactical use of such interruptions while protecting legitimate medical treatment.

Under the relevant conditions, the coach must nominate an outfield player to leave temporarily when the goalkeeper requires treatment.

The nominated player stays off for at least one minute after play restarts.

But this is where the trial differs from the ten-second substitution rule.

Once the minute has elapsed, the nominated player may return with the referee’s permission. If the ball is still in play, that return can take place from the touchline. The player does not necessarily have to wait for the next stoppage.

The decision about who leaves must also be made quickly.

Under the coach-nominated version used in the English trial, the manager has ten seconds to select an outfield player. If no player is nominated in time, the captain becomes the designated player.

That means a goalkeeper’s treatment can present the coach with an unexpected selection decision.

Not which replacement to bring on.

Which player can the team afford to lose temporarily?

Choosing who leaves may be harder than it sounds

Imagine another hypothetical situation.

A team is protecting a narrow lead when a goalkeeper-injury stoppage triggers the trial procedure.

The coach could nominate a striker. That would preserve the back line and most of the midfield’s defensive coverage.

But who receives the ball if the defenders clear it long?

Without a forward outlet, the team may struggle to escape its own half. The opposition could collect possession and launch another attack.

Alternatively, the manager could nominate a wide midfielder and keep the striker available.

That might provide a better route forward, but it could also leave one full-back without the usual support.

An opponent might notice the opening and move extra players towards that flank.

The choice is therefore not simply about removing the least important player.

It depends on the match situation, the team’s existing organisation and the attacking threat the opponent can create.

A side chasing a goal may prefer to preserve more players near the opposition penalty area. But leaving too little cover behind them could make the next counterattack far more dangerous.

The answer should be prepared around the players and responsibilities the team actually has, rather than an improvised new formation nobody has practised.

And all of these examples are conditional. They explain possible decisions under the rules, not mistakes made by a named manager in an actual match.

An injured goalkeeper is not evidence of time-wasting

There is an important boundary around the new trial.

The purpose is to discourage unnecessary delay, not to punish players for needing medical treatment.

The ten-second substitution procedure already recognises injuries and safety concerns.

The goalkeeper trial contains its own protections, including exceptions for serious injuries, bleeding, certain collisions in which both the goalkeeper and an outfield player need treatment, and specified injuries resulting from physical offences.

The full protocol also deals with situations where further treatment becomes necessary.

These are not technicalities to be ignored for the sake of a more dramatic football story.

A goalkeeper requiring treatment has not automatically done anything wrong. Nor should a team be encouraged to avoid medical attention because it fears being temporarily short-handed.

The referee must apply the relevant conditions and safeguards.

The sporting consequences matter, but player safety comes first.

The next question comes before the next substitution

MATCHIQ has previously examined how managers change matches from the touchline.

Against Lille, Arsenal scored their first goal before three prepared substitutions were made. The replacements helped produce further goals, but not everything that followed could be credited to their introduction.

Against Ipswich, Fulham’s late difficulties raised another question: when a team is defending a lead, does it still have the midfield support and forward outlet needed to escape pressure?

Those cases dealt with who was selected, when changes happened and how the available evidence related to the result.

The new rules introduce another consideration.

What if the chosen replacement cannot enter immediately? Or what if a goalkeeper-injury stoppage requires the temporary removal of a player from somewhere else in the team?

The coach must still protect the purpose of the original plan.

That may mean preparing substitutes more carefully, making sure players understand how to leave promptly, and agreeing in advance who covers the centre or the flanks during a temporary numerical disadvantage.

It may also mean deciding which outfield role can be sacrificed most safely if the goalkeeper trial is triggered.

But there is a strong reason not to exaggerate the consequences.

Most professional substitutions can be completed within the permitted time. The protocols include exceptions for legitimate medical and safety circumstances.

And while the rules create the possibility of temporary numerical disadvantage, we do not yet have a sufficiently verified set of match incidents to say how frequently that disadvantage occurs or how often it changes results.

It would be wrong to describe every late goal after a substitution as a consequence of the new procedure.

The evidence needed is much more specific: when the restriction was triggered, who left, how long the team actually played short-handed, how the remaining players adjusted and whether the opponent exploited the gap.

Until then, the conclusion should remain precise.

A coach can make the right substitution and still need a plan for the moments before the replacement enters. A goalkeeper can require legitimate treatment while the manager faces an additional decision about the outfield players.

The new rules have changed what teams must prepare for. Whether that one-minute gap changes matches is the next question football must answer.
