NRL bends its own rules so Jai Arrow can reach 100 games for South Sydney after MND diagnosis
Australia's National Rugby League has rewritten its own interchange regulations so that Jai Arrow, the South Sydney forward forced to medically retire this year after a motor neurone disease diagnosis, can take the field one last time and bring up 100 appearances for the Rabbitohs.
The governing body approved one-off rule changes allowing South Sydney to carry an additional player on their team sheet and use an extra interchange across the club's final two fixtures of the 2026 regular season — away to the Gold Coast Titans on Saturday, then a home game against the Sydney Roosters on 4 September (BBC Sport).
Arrow, 30, played 98 times for Souths after joining the club in 2021. Those two remaining games would normally have been out of reach once he was medically retired in May following his MND diagnosis. Under the arrangement confirmed by the NRL, he will lead the team out in full kit, take part in the opening seconds, then leave the field as the Rabbitohs' first interchange and take his place on the bench for the rest of the match (NRL.com).
Motor neurone disease is a progressive illness that attacks the nerve cells controlling voluntary muscle movement, gradually robbing the body of the ability to walk, speak, swallow and breathe. There is no known cure.
Arrow's 10-year NRL career spanned 178 games across the Brisbane Broncos, the Gold Coast Titans and the Rabbitohs, plus 12 State of Origin appearances for Queensland — the annual best-of-three series between rugby league's two traditional heartland states and the fierhest rivalry the sport knows.
He spoke publicly for the first time about his diagnosis at a press conference in May, saying he was "ready to fight," and later issued an emotional plea centred on his family (Nine.com.au). Arrow has said he will not be able to control his emotions when he leads Souths out in the final two rounds (Fox Sports).
Rabbitohs chief executive Blake Solly said the club was "very grateful" to everyone who helped accommodate the request. He said the arrangement would provide "great inspiration for everyone watching," and that MND "will not hold Jai, or anyone else, back from achieving what they want to achieve in life" (BBC Sport).
The rugby community on both sides of the world knows this illness only too well. Former Queensland forward Carl Webb died of MND in 2023, aged 42. Leeds Rhinos and England half-back Rob Burrow died in 2024, five years after his diagnosis. Scotland rugby union international Doddie Weir died in November 2022. World Cup-winning England flanker Lewis Moody was diagnosed in September 2025.
Each name belongs to a different corner of the rugby world. The thread connecting them is the same relentless disease — and a sport that keeps finding ways to stand alongside those it strikes.
