Jai Arrow announced his immediate retirement from the National Rugby League after doctors diagnosed him with Motor Neurone Disease (MND) in May 2026 [1, 2]. The 30-year-old played 178 NRL games over a 10-year career with the Brisbane Broncos, Gold Coast Titans, and South Sydney Rabbitohs. He also made 12 State of Origin appearances for Queensland [1, 2].
Arrow had not played in the 2026 NRL season, as he experienced symptoms initially thought to be a shoulder injury during pre-season [2]. After extensive medical testing and specialist reviews, he confirmed his diagnosis relates to MND, a neurological condition that affects the brain and spinal cord nerves controlling muscles, leading to progressive muscle weakness and stiffness [1, 2].
"On medical advice, I am not currently medically cleared to train or play at the required level," Arrow said. "I will be stepping away from those duties while I focus fully on my health, treatment, and rehabilitation" [1].
Arrow received strong support from his South Sydney Rabbitohs teammates, staff, and family during this difficult period. Rabbitohs coach Wayne Bennett called him "a special guy" and praised him as an honest, hardworking player and devoted family man who had given much to his teams and communities [2].
Arrow was awarded the George Piggins Medal as the Rabbitohs' best player in 2025 and was recognized for his community contributions [2].
MND has no known cause but is thought to result from genetic and lifestyle factors. Around 2,750 people live with MND in Australia [1, 2]. Several former rugby players have died from the disease, including Carl Webb, Rob Burrow, and Doddie Weir, while Lewis Moody was diagnosed last year [1].
Arrow’s announcement on May 20, 2026, came after months of symptoms and medical assessments that ruled him medically unfit to continue playing [1, 2]. He did not play in any 2026 NRL matches due to these issues [2].
