An uncontested scrum guarantees possession; it is not an automatic response to every injury or card.

The ruleset used on this page

This page applies the World Rugby Laws of the Game Rugby Union 2026, including the Sevens variations to Laws 3 and 19 and the law assets updated on 1 July 2026. World Rugby says the July changes apply to new competitions or events starting after 1 July; a competition already in progress must confirm its implementation date with the relevant union.

The scope is rugby union sevens governed by World Rugby's law framework. A national union, school, age-grade body, festival or tournament may add an approved safety protocol. That supplementary document controls the trigger and administration only for the competition that adopted it.

Exactly what “uncontested” changes

The World Rugby definition contains two linked requirements:

• Guaranteed possession: the team entitled to throw in gains the ball without opposition contest.
• No push: neither pack is allowed to push from the mark.

The original reason for awarding the scrum does not change. There is no automatic score, penalty or change of throw-in merely because the scrum is uncontested. The team already entitled to throw in keeps that entitlement and is now assured possession.

The 15-a-side trigger is deleted

General World Rugby Law 3.13 says scrums become uncontested when a team cannot field a suitably trained front row or the referee orders it. Law 3.16 then gives the process after a front-row injury, yellow card or red card. The published Sevens variation deletes Law 3.13 and Laws 3.16–3.20.

Those deleted clauses must not be imported back into sevens as though they still applied. The Sevens variation leaves Law 3.14, which permits a match organiser to stipulate conditions under which a game may start with uncontested scrums, but it supplies no replacement mid-match trigger or restoration procedure. A tournament that wants a wider protocol needs to state it.

A World Rugby sevens scrum is contested

The Sevens variation to Law 19.5 requires three players from each team in the scrum, with all three remaining bound until it ends. Law 19.4 shortens the time to be ready: the teams must be ready to form within 15 seconds of the referee making the mark, or the sanction is a free-kick.

There is no reduced-force assumption in that wording. In an ordinary sevens scrum the teams may push once the ball is thrown, front-row players may strike for it, and possession can be contested within Law 19. The smaller three-player formation does not itself make the scrum uncontested.

It is still a formal scrum restart

Unless the competition regulation expressly modifies the mechanics, the rest of Law 19 continues to govern the uncontested restart. That means:

• the referee makes the mark in the scrum zone;
• three players from each sevens team bind and remain bound until the scrum ends;
• the front rows form square, stable and stationary through the referee's “crouch, bind, set” sequence;
• the hooker uses the brake foot during “crouch” and “bind”;
• the scrum-half throws without delay once both sides are stable, and the putting-in hooker strikes for the ball;
• non-participants stay at least five metres behind their team's hindmost foot, subject to the try-line exception; and
• the scrum offside lines remain until the scrum has ended.

“Guaranteed possession” does not permit the putting-in side to ignore binding, throw-in, striking, offside or ending requirements. It removes the opposition's contest, not the structure of the restart.

The packs stabilise; they do not drive

The prohibition begins from the mark and applies to both teams. There is no legal “small shove”, timed hit after the throw, wheel, or drive to disturb delivery. The non-throwing team also cannot manufacture a contest for possession that the definition expressly removes.

Players still need enough shape and pressure to form safely, but stability is not a licence to move the opposition. The referee should make the uncontested status clear before formation so neither pack mistakes normal engagement for permission to drive.

Possession is guaranteed, but the ball must still emerge

Under Law 19.16, the scrum begins when the ball leaves the scrum-half's hands. The putting-in side then wins it without opposition contest. In sevens, the variation to Law 19.36 says the scrum ends when the ball comes out other than through the tunnel, when that team's scrum-half plays it, when the referee whistles for an infringement, or when the ball is on or over the try line.

Until one of those ending events occurs, participating players remain bound and scrum offside lines still apply. A defender who advances merely because possession is certain can therefore be penalised for offside.

Uncontested does not mean risk-free

Law 19 still requires safe body height, feet on the ground, legal prop binds and a square, stable formation. Law 19.25 requires an immediate whistle if the scrum collapses or a player is lifted or forced upwards. Law 19.37 makes charging, pulling, intentional lifting, intentional collapse, and intentionally falling or kneeling penalty offences.

Law 7.3 forbids advantage when a scrum player is lifted or forced upwards, or whenever continuing would be dangerous. More generally, Law 6.8 gives the referee power to stop play at any time and requires a whistle when it would be dangerous to continue.

First ask whether three players can scrum safely

A card reduces the number of players on the field, but does not by itself alter the scrum's contested status. If a six-player team can still provide the three players required by Sevens Law 19.5 and form safely, those three pack down and the team has fewer players outside the scrum.

An injury is handled through the applicable replacement law and competition medical process. If the available players cannot form the scrum required by Law 19.5 safely, officials must not improvise the deleted 15-a-side procedure. They must apply the appointed event protocol. If no lawful safe continuation is available, Law 5.10 allows the referee to suspend or end the match rather than permit unsafe play.

The actual infringement determines the outcome

“The scrum is uncontested” is not a single catch-all sanction. An early push before the ball is thrown can fall under Law 19.17 and bring a free-kick. Dangerous charging, pulling, lifting or intentional collapse under Law 19.37 brings a penalty. Illegal binding and offside also carry their stated Law 19 sanctions.

For a technical infringement, the referee may apply Law 7 advantage only if the benefit is clear and real. For lifting, forced upward movement or any dangerous continuation, the referee must stop play immediately. Serious or intentional dangerous conduct can also require foul-play discipline; uncontested status does not protect a player from a card.

What a usable local protocol must answer

A competition instruction should do more than say “scrums may be uncontested”. Players and officials need to know:

1. The trigger: start-of-match condition, injury, cards, shortage of trained players, pitch condition, or a defined age-grade rule.
2. The decision-maker: referee, medical official, team declaration, tournament director, or a combination.
3. Player numbers: how many pack down and whether either team loses an additional player.
4. Replacement consequences: who may enter, whether a tactically replaced player may return, and whether the team remains short.
5. Scrum mechanics: whether the standard three-player bind, engagement and throw are retained.
6. Restoration: whether and when contested scrums resume.
7. Match consequence: whether inability to comply leads to continuation, forfeiture, suspension or abandonment.

If the regulation does not answer those points, the gap should be resolved with the organiser before play, not invented after an injury.

A yellow card leaves six players

Situation: a player is suspended and the team has six players on the field. Three available players can form a legal, safe scrum. The event has adopted no special uncontested-scrum protocol.

World Rugby 2026 ruling: the scrum remains contested. Three players from each team bind under the Sevens variation to Law 19.5; the short-handed team has only three players outside the scrum. The decisive fact is that the Sevens variation deletes the automatic 15-a-side card procedure.

The event starts all scrums uncontested

Situation: an organiser's published rules, issued under World Rugby Law 3.14, state before the event that every scrum will be uncontested and retain the normal three-player sevens formation.

World Rugby 2026 ruling: the team throwing in gains possession and neither side pushes. The three players still bind and remain bound, and offside lines still apply, unless the same event rules make another express modification. The decisive fact is the organiser's pre-match rule, not the age or assumed ability of the players.

A defender shoves after the throw

Situation: both teams were told the scrum is uncontested. After the ball enters, the non-throwing pack drives forward to disrupt delivery.

World Rugby 2026 ruling: the drive is illegal because neither side may push from the mark. The referee stops unsafe action and identifies the exact Law 19 offence and sanction; a dangerous charge, lift or intentional collapse is a penalty under Law 19.37. The decisive fact is that a normal post-throw push is displaced by the uncontested-scrum definition.

The scrum becomes unstable before the ball enters

Situation: an uncontested scrum cannot become square and stable, and one player begins to rise under pressure.

World Rugby 2026 ruling: the referee does not allow the throw. If a player is lifted or forced upwards, Law 19.25 requires an immediate whistle and Law 7.3 prevents advantage. The referee resets if there was no infringement or applies the relevant sanction if there was one. The absence of a push contest does not lower the stability test.

How to decide whether a sevens scrum is uncontested

1. Name the event and rules edition. For this page, the baseline is World Rugby 2026 with the 1 July update.
2. Read the Sevens variations. Do not apply the general 15-a-side Law 3 trigger that sevens deletes.
3. Check the organiser's supplement. Identify an express trigger, player-number rule and restoration process.
4. If no supplement applies, use the normal contested scrum. Three players per side must be ready within 15 seconds and remain bound.
5. If an uncontested scrum is authorised, preserve the restart. The throwing team gains possession; neither side pushes; other Law 19 duties continue unless expressly modified.
6. Stop danger immediately. Apply Laws 5, 6, 7 and 19 rather than allowing an unsafe formation.

Claims the 2026 laws do not support

• “Sevens scrums are normally uncontested.” No. The standard World Rugby sevens scrum is a three-player contest.
• “Any front-row injury forces uncontested scrums.” That is the general 15-a-side process; its operative clauses are deleted in the Sevens variation.
• “A card automatically removes the contest.” No. First apply the sevens player-number and scrum laws plus any express event protocol.
• “The referee can invent any procedure in the name of safety.” The referee can stop, suspend or end unsafe play, but competition administration must come from the appointed rules.
• “Uncontested means no binding or offside lines.” It remains a scrum restart unless the organiser expressly changes those mechanics.
• “Guaranteed ball means play has already restarted.” The scrum begins only when the ball leaves the scrum-half's hands and ends only under Law 19.36 as varied for sevens.
