Known more commonly as 'the bunker', the process has been trialled at a number of high-profile tournaments since its launch. Those include Men’s Rugby World Cup 2023 and the last two editions of the Women’s Six Nations.
It was created to help match officials make correct decisions while promoting game continuity. But how does it work?
When is the bunker used?
Referees remain the lead decision-maker on the pitch. However, they now have the ability to refer any foul play incident for formal review.
If the officiating team is unable to determine whether an incident warrants a red card after two big-screen replays but agree a yellow card threshold has been met, the referee will send the player to the sin bin for ten minutes and cross their arms to signal a formal review.
How does it work?
Located in the ‘bunker’, a dedicated Foul Play Review Official (FPRO) will then have up to eight minutes to review the incident using all available footage and technology, including Hawk-Eye split screen and zoom technology.
They will then determine the outcome and relay their decision to the on-field match officials and referee.
The FPRO will either uphold the yellow card and enable the player to return or upgrade to a red card with the player staying off the field, unable to be replaced.
Can a player still receive a straight red card?
Yes. If the on-field officiating team determines that an act of foul play that warrants a red card has been committed then they can send a player off without the need for a bunker review.
