South Sydney and former Queensland State of Origin enforcer Jai Arrow will retire from the NRL immediately after being diagnosed with motor neurone disease.

Souths chief executive Blake Solly revealed the devastating diagnosis on Wednesday.

Arrow remained silent during Souths’ press conference while he sat alongside Solly as he delivered the harrowing news.

Only 30 years old, Arrow has played 98 games for the Rabbitohs since Wayne Bennett lured the classy forward to the club in 2021 after handing the then-25-year-old his first-grade debut at Brisbane a decade ago.

Arrow proposed to his fiancée Berina Colakovic during a romantic post-season holiday in Italy in October 2024.

That December, the loved-up couple took to Instagram to reveal they were expecting their first child together.

Their daughter Ayla Rae was born in April 2025.

‘After extensive medical testing and consultations regarding ongoing symptoms, I’ve recently received a diagnosis relating to a nerve and neurological condition,’ Solly said on Arrow’s behalf.

‘Further tests, specialist reviews and medical processes are still ongoing, and my doctors are continuing to assess my condition.

‘Over recent months, my symptoms have affected different parts of my everyday life.

‘On medical advice, I’m currently not medically cleared to train or play at the required level, and I’ll be stepping away from those duties wile I focus fully on my health treatment and rehabilitation.

‘What I need right now isn’t sympathy or sadness. What I need is support, understanding, and privacy while my family and I navigate this difficult time.’

Bennett praised Arrow, saying the Bunnies star ‘always puts his family and his team first’.

‘This is a difficult time for Jai and his family, however, we want to pay tribute to him for everything he has given his teammates, his coaches and his communities in Brisbane, the Gold Coast, the people of Queensland, and here in Sydney,’ Bennett said.

The 30-year-old star stamped himself as one of the league’s best forwards as he played a total of 178 NRL games for the Broncos, Titans and Rabbitohs

‘Most importantly, we pay tribute to him for the family man he has become.

‘He is a special guy and we’re all very lucky to have him at our club and in our lives.’

Solly stressed that Arrow, his partner and daughter are ‘very much part of the Rabbitohs family’.

‘We all know how difficult the past few months have been for Jai, but we also know that he will fight this illness with the same bravery, passion and character that was the hallmark of his playing career.’

The tough forward is hugely respected in NRL circles and won the George Piggins Medal in 2025 as the Rabbitohs’ player of the year.

He also won the Bob McCarthy club person of the year award in 2025, the Souths Cares Award for outstanding contributions to the community and The Burrow Appreciation Award in 2024.

Arrow was also a finalist for the NRL’s Ken Stephen Medal in 2025 for his work with Souths Cares, Whatability and Vinnies Vans.

Arrow also had four seasons at Gold Coast following his two-season stint at the Broncos and played 12 games for Queensland between 2018 and 2023.

He helped the Maroons win series in 2020, 2022 and 2023 while also playing in the Rabbitohs’ 2021 grand final loss to Penrith.

Arrow’s diagnosis comes two and a half years after former Maroons hardman Carl Webb died of MND aged 42.

The rugby league world was also rocked when Western Suburbs, Balmain and North Sydney great Scott Gale died of the debilitating condition at just 39 in 2004.

Motor neurone disease is a rare condition that mainly affects people in their 60s and 70s, but it can hit adults of all ages.

It’s caused by a problem with cells in the brain and nerves called motor neurones. These cells gradually stop working over time. It’s not known why this happens.

Motor neurones control the muscles responsible for movement, speech and breathing.

Early symptoms can include weakness in your ankle or leg, like finding it hard to walk upstairs; slurred speech, finding it hard to swallow, a weak grip, and gradual weight loss.

MND has also struck in the AFL, with footy legend Neale Daniher diagnosed with the condition in 2013.
