Katoa, currently a player for the Melbourne Storm, first encountered trouble when he was accidentally hit in the head by fullback Lehi Hopoate’s shoulder during the pre-game warm-up. Despite this initial incident, team doctors assessed him and deemed him fit to play.

During the game, Katoa had to leave the field early to undergo a Head Injury Assessment (HIA) after being involved in another heavy collision. He was able to pass the assessment and returned to the field.

Unfortunately, a third head injury in the second half forced him out of the game for good. The Tonga bench responded quickly, placing an oxygen mask on him before he was stretchered off and transported to Auckland Hospital for further evaluation.

However, a third knock in the second half ended his night and prompted immediate concern from the Tonga bench, where medical staff fitted him with an oxygen mask before he was stretchered off and taken to Auckland Hospital.

Woolf confirmed Katoa had shown signs of deterioration after the final hit but insisted the medical team followed all required protocols.

‘The doctors did the usual HIA [head injury assessment]; we’ve got two very experienced doctors there,’ Woolf said.

He was eventually taken from the field and required medical attention before being taken to hospital

Tonga coach Kristian Woolf said medical staff had followed all of the correct protocols

‘They’ve done their usual HIA and he’s passed all that and passed all that well.’ 

Woolf said Katoa was cleared because he showed no symptoms at the time of testing.

‘Unfortunately I think he’s copped a second hit that was quite heavy and there’s been a poor result off the back of that,’ he said. 

The Tongan coach said Katoa was alert when he left the field but began to feel unwell on the sideline, prompting his transfer to hospital.

‘He wasn’t great on the sideline; I’m told he was responsive and was improving before he actually went to the hospital,’ Woolf said. 

Tonga Rugby League president Lord Fakafanua confirmed Katoa remained under medical observation and would not fly home with the team. Officials visited him in hospital after the match and said he would be monitored for several days.

Katoa later reassured fans on social media, quoting the Bible verse ‘I can do all things through Christ who strengthens me’ and thanking supporters for their messages.

Despite the distressing scenes, Woolf maintained his faith in Tonga’s medical staff, saying they made the right calls at each stage of the process.

‘My job is not to question doctors,’ he said. 

‘They were both comfortable with that and comfortable with him coming on to the field.’
