Illustrative example—not a real match: Imagine North RFC’s flanker makes a tackle that appears to contact an opponent’s head. The referee sees enough to issue at least a yellow card, but the available on-field view does not make a red-card decision clear. In a competition using the Foul Play Review Bunker, the referee can send the incident for an off-field review while the game continues. The player serves the yellow-card period as the review takes place.
The Bunker is the off-field foul-play review process. It is designed to let an additional match official inspect footage during live match time, reducing a long on-field stoppage. It does not mean every yellow card is automatically reconsidered, and the exact red-card replacement rule depends on the competition. Here is how North RFC’s hypothetical incident would move through the process.
The referee remains the lead on-field decision-maker. The Television Match Official (TMO) is the match official who supports decisions using video. Where appointed, a Foul Play Review Officer (FPRO) is an additional official who reviews referred foul-play incidents off the field. Fans may hear the whole process called “the Bunker,” but that nickname refers to the review system, not a separate team that takes over the match.
A “sin bin” is the area where a temporarily suspended player must remain away from the field. Under the standard rugby union law, a yellow card means the player is cautioned and suspended for 10 minutes of playing time. The clock is match time, not necessarily 10 minutes of wall-clock time: a lengthy injury stoppage does not make the player’s suspension disappear faster.
In the example, the referee and other officials first decide whether the tackle is foul play and what minimum sanction is justified. They can consult the TMO and look at the available big-screen or sideline replays. If the officials determine that a permanent red card is already clear—such as for intentional, highly dangerous foul play under the relevant protocol—the referee can issue it directly. The Bunker is not a required extra stage for every red card.
If the evidence meets at least the yellow-card threshold but does not yet settle whether a red card is warranted, the incident may be referred for formal off-field review where that process is operating. In the World Rugby process, the referee signals the referral by crossing the arms above the head after showing the yellow card. North RFC’s flanker leaves the field for the temporary suspension; the match can restart rather than waiting through every video angle.
The carded player goes to the sin bin and the team plays with one fewer player. The FPRO examines the incident using available footage and technology, which can include different camera angles and replay speeds. World Rugby’s published process gives the FPRO up to eight minutes to complete the review. That review occurs during live match time, inside the 10-minute yellow-card period; it is not an extra eight minutes added to the suspension.
For North RFC, the question is whether the tackle stays at yellow-card level or meets the higher red-card threshold. The review is about the incident and the appropriate sanction under the laws and competition protocol. It is not a coach’s appeal, and a player’s team cannot demand that the review produce a particular result. The referee and review official communicate through the match-official system; television replays shown to viewers are not necessarily every angle the officials can access.
In World Rugby’s process, the review official advises the referee whether the yellow card should stand or be upgraded under the applicable protocol. The referee communicates the outcome to the players and match officials. The main paths are:
| Review outcome | What happens to the player | What happens to the team |
|---|---|---|
| Yellow card confirmed | The player remains off until the 10-minute playing-time suspension has been served, then may return as allowed by the laws. | The team plays short-handed during the temporary suspension. |
| Red-card sanction under an adopted 20-minute replacement trial | The player cannot return to the match. | In eligible elite competitions, the team may use an available replacement after 20 minutes of playing time from the incident. |
| Permanent red card | The player is dismissed for the remainder of the match. | The player is not replaced, so the team remains short for the rest of the match. |
In North RFC’s hypothetical match, suppose the review confirms the yellow. The flanker stays in the sin bin for the full 10 minutes, after which the team can restore its playing numbers according to the referee’s timing and substitution procedures. If the review instead upgrades the sanction, the same player cannot come back. Whether a substitute can restore the team to 15 players later is a separate question governed by the competition’s red-card rules.
Do not treat “red card” as a single universal team-number outcome in every 2026 rugby match. World Rugby’s August 2025 implementation guidance describes a Global Law Trial for elite rugby only. Unions decide what counts as elite in their jurisdictions, and competitions must specify how they will apply the trial. Under the trial, some red-carded players cannot return, but an available replacement can enter after 20 minutes of playing time for eligible red-card incidents. For intentional, highly dangerous acts, the permanent red remains and the dismissed player cannot be replaced.
In a match with both a TMO and FPRO, the guidance says the FPRO can recommend that the yellow remain or be upgraded to a 20-minute red-card replacement. The FPRO does not recommend a permanent red through that off-field review; the referee can issue a permanent red directly after the on-field review where the criteria are met. If a match has no FPRO, the TMO may perform the off-field review if the competition’s setup permits. Some elite games may lack the staffing or technology for an off-field review, and then the on-field officials decide the sanction at the time.
World Rugby’s 2026 Men’s Six Nations official note said foul play meeting the yellow threshold should go to the Bunker for review, while permanent red cards remain for intentional foul play. That describes the competition approach announced for that tournament; it should not be assumed to govern every domestic league, age grade, sevens event, or community match. As of September 2026, World Rugby describes the 20-minute replacement as a law trial running through 2026 for later Council review.
When you see a player shown yellow and the referee cross the arms overhead, follow this sequence:
For North RFC, the viewer should not assume that the player returns just because the first card was yellow, or that the team stays down to 14 for the whole match if the review ends in a red. The review’s outcome and the adopted red-card procedure both matter.
The Bunker lets officials review a serious foul-play incident away from the field while the match continues. In the hypothetical North RFC tackle, the referee first establishes at least a yellow-card threshold, the player leaves for 10 minutes, and the FPRO reviews available footage for up to eight minutes. The yellow can stand, or the sanction may be upgraded under the competition’s rules. If upgraded, the player is done for the match; whether the team can replace that player after 20 minutes depends on the adopted elite-game trial and the type of red-card sanction.
