ScopeWhich rules this page applies
The baseline here is International Rugby League (IRL), Laws of the Game 2026, effective from 1 January 2026, especially Section 11, “The Tackle and Play-the-Ball.” IRL made the player's sequence more explicit for 2026 and confirmed that dropping the ball onto the ground while trying to play it is a knock-on.
Domestic competitions may change how a defensive ruck offence is restarted. One important current example is Australia's NRL: its announced 2026 rules moved the field-position threshold for certain set-restart infringements from 40 metres to 20 metres from the possession team's goal line. That is an NRL variation, not the wording of the IRL international law.
Terminology: rugby league commentators call the space around the tackled player “the ruck.” It is not the rugby-union ruck formed by players binding over a ball on the ground. League restarts with a prescribed play-the-ball.
Step 1When is the tackle complete?
The duties at the play-the-ball begin only after a tackle has been completed. Under IRL 2026, common completion points include these:
- The ball-carrier is held by one or more opponents and the ball or the hand or arm holding it touches the ground.
- The ball-carrier is held upright and cannot make further progress or part with the ball.
- The ball-carrier, while held, makes it clear that they have succumbed and want to be released to play the ball.
- An opponent places a hand on a player who is already lying on the ground in possession.
- A standing ball-carrier has a leg lifted above the horizontal by defenders. The referee calls the tackle immediately for player safety.
The referee's “held” or tackle call fixes the transition. A defender cannot treat the next moment as extra time to wrestle for possession, and the attacker cannot continue running simply because the whistle has not sounded.
Step 2Defenders must release immediately
When the tackle is complete, tacklers must immediately release the tackled player and move away far enough to allow the legal restart. They must not hold the player down, keep a hand on the ball, pull a leg, crowd the space needed to stand, or lie in the route of the ball.
“Immediately” still allows the physical action needed to disengage safely; it does not give the defence a free pause. The referee judges the whole tackle: body positions, whether a defender could reasonably move, whether the attacker is preventing that movement, and whether the delay affected the next play.
The key distinction: completing a legal tackle is permitted. Continuing to control the attacker after the tackle is complete is where defensive ruck interference begins.
Step 3The tackled player's exact sequence
IRL's 2026 wording gives the ball-carrier a clear order of actions:
- Regain the feet without delay at the place where the tackle occurred.
- Lift the ball clear of the ground. It must be controlled rather than abandoned on the turf.
- Face the opponents' goal line.
- Place the ball on the ground in front of the foremost foot.
- Make a genuine attempt with that foot to play the ball backwards.
The player must not crawl forward, step deliberately away from the mark, obstruct the marker, or rush the action before tacklers have had a fair opportunity to release and clear. The law protects a prompt restart, not an artificially manufactured infringement.
2026 clarification: if the tackled player drops the ball onto the ground during this process, IRL says it is a knock-on. That is different from controlling it, placing it and making the required foot action.
Step 4The marker's narrow legal position
One defender may take up the marker position immediately opposite the tackled player. The marker has special access to the next play, but also special restrictions:
- The marker must be directly opposite and square at the play-the-ball.
- The marker cannot kick or heel the ball as the tackled player plays it.
- The marker cannot interfere before the ball has been played backwards.
- A defender who did not establish the legal marker position cannot gain marker privileges simply by standing near the ruck.
The marker is not required for the restart to occur. If no opponent takes the position, play can continue; the defence does not get to delay the play-the-ball while it appoints one.
Step 5Everyone else retires ten metres
Other defenders must retire at least ten metres from the point at which the ball is played, or to their own goal line if that is closer. They cannot advance until the ball has cleared the ruck. A defender may therefore be guilty of offside even when both players beside the ball are perfectly legal.
This produces two separate questions for officials:
- At the ball: did the tacklers release, did the tackled player restart correctly, and was the marker square?
- Away from the ball: did the defensive line retire the required distance and wait for the ball to clear the ruck?
A fast defensive line is legal only if it began from an onside position and advanced at the legal moment.
Ball liveWhen can dummy-half move it?
The ball is in play when the tackled player has played it backwards. The acting half, commonly called dummy-half, can then pick it up, pass, kick or run subject to the other laws.
IRL 2026 also deals with an empty ruck. If there is no marker and no acting half present, the ball is deemed clear immediately after it is heeled backwards. The tackled player may regain possession and play on. An opponent cannot demand that the attack wait for a dummy-half who is not there.
This timing matters to the defensive line: “ball clear of the ruck” is the trigger to advance, not the first receiver catching a pass several metres away.
Defensive faultsWhat counts as ruck interference?
Typical defensive infringements include holding down after completion, keeping a hand or arm on the ball, crowding the standing space, dragging or pulling the tackled player after “held,” failing to roll away, splitting from marker before the ball is in play, or advancing from an offside position.
Not every untidy tackle is automatically a defensive offence. A referee may allow play to continue where the defender has made a genuine immediate effort to release, where the ball-carrier has trapped the defender, or where no illegal delay or interference occurred. Repeated, deliberate or tactical offending can be treated more severely than an isolated technical infringement.
Do not judge from speed alone: a slow play-the-ball can be legal, and a very fast one can be illegal. The cause of the delay—and whether both sides followed their duties—is what matters.
Attacking faultsThe ball-carrier can infringe too
The attack does not receive an automatic decision whenever a defender is near the play-the-ball. The tackled player can offend by:
- Moving materially away from the place of the tackle to steal distance or escape the marker.
- Failing to get upright and follow the prescribed placement-and-foot sequence.
- Dropping or losing control of the ball, which can be a knock-on.
- Playing the ball before tacklers have had an opportunity to clear.
- Holding or trapping a defender to create the appearance of interference.
- Using the body or ball to obstruct the marker.
The exact restart depends on what went wrong: a knock-on, an incorrectly performed play-the-ball, obstruction and misconduct are not interchangeable. Officials identify the first material offence and apply the restart set out for it rather than calling every attacking error a generic “ruck penalty.”
SanctionsSix again or a penalty?
Under the IRL 2026 international law, interference by a defender at the play-the-ball and markers splitting early generally bring a tackle-count restart. If the offence occurs within the 40-metre zone measured from the possession team's own goal line, the international law prescribes a penalty instead. Intentional delay of the play-the-ball is also listed for a set restart, while foul play and misconduct can require stronger action.
The field-position threshold is competition-sensitive. The NRL's 2026 announced change uses 20 metres rather than 40 metres for certain set-restart infringements. Leagues may also publish interpretations dealing with repeated infringements, professional fouls and sin-bin thresholds.
Practical rule: identify the governing competition before declaring that a ruck offence “must” be six again or “must” be a penalty. The underlying duty may be the same while the restart differs.
Worked case 1The ball is dropped before the foot action
Situation: the player stands, lets the ball fall onto the turf and swings a foot over it.
IRL 2026 ruling: knock-on. The 2026 amendment expressly says that dropping the ball onto the ground in this sequence constitutes a knock-on; merely swinging a foot does not cure the earlier loss of control.
Worked case 2A tackler lies across the ball near halfway
Situation: the tackle is complete around halfway. A defender can move but remains across the ball and delays the restart.
IRL 2026 ruling: defensive interference, ordinarily producing a tackle-count restart because the offence is outside the 40-metre zone from the possession team's goal line. Deliberate or repeated conduct can still attract further sanction.
Worked case 3The same delay deep in the attacker's half
Situation: the possession team is restarting within 40 metres of its own goal line and the defender illegally slows the play-the-ball.
IRL 2026 ruling: penalty under the international field-position exception. In the NRL, check the 2026 20-metre threshold and the precise category of infringement instead of importing IRL's 40-metre line.
Worked case 4The marker kicks at the ball
Situation: the marker is square, but tries to heel or kick the ball as it is played.
IRL 2026 ruling: illegal. The tackled player must make the genuine backward foot action; the marker is expressly forbidden from kicking or heeling the ball at that restart.
Worked case 5Nobody stands at marker or dummy-half
Situation: the ball is legally heeled backwards but neither an opponent nor an acting half is present at the ruck.
IRL 2026 ruling: the ball is immediately clear. The tackled player may recover it and continue. The defensive line's right to advance also follows the ball-clear trigger.
Decision pathHow to analyse any replay
- Find the tackle-completion moment. Do not start with the play-the-ball in isolation.
- Fix the mark. Note where the tackled player must regain the feet.
- Watch the release. Ask whether tacklers could and did disengage immediately.
- Watch the attacker's hands, feet and facing. Control, placement and a genuine foot action are separate requirements.
- Check marker and defensive line separately. Square at the ruck is not the same as ten metres onside.
- Identify the first material infringement. An attacker cannot necessarily manufacture a call after offending first.
- Name the competition and version. Only then choose set restart, penalty, turnover or disciplinary action.
Common mix-upsFour shortcuts that give the wrong answer
- “The defender was trapped, so the defence offended.” Not necessarily. Ask who created the trap and whether the defender made an immediate genuine effort to clear.
- “The ball touched the foot, so it was legal.” The 2026 sequence also requires control, correct position, facing, placement and a genuine backward action.
- “The marker was square, so nobody was offside.” The ten-metre defensive line has its own test.
- “Every ruck offence is six again.” Field position, the kind of offence, repetition, misconduct and the competition's variation can change the outcome.
