The Sydney Roosters have referred an incident involving Dylan Napa to the NRL integrity unit after the star forward was allegedly knocked out at a party.
News Corp Australia reports Napa was coming to the aid of a woman when he was struck with a fire poker by another party-goer on Sydney's northern beaches.
The Roosters player was allegedly asleep at the Palm Beach property when he was awoken by screaming, and he saw a man destroying property and yelling at a woman.
He was reportedly knocked unconscious when he was hit.
Two other people were injured in the incident, and all three were taken to hospital.
They were later released.
Six hundred people attended the party at the Palm Beach mansion.
It's an annual charity event called "Palmbu" in support of the Vasculitis Foundation.
The Roosters issued a brief statement saying they were aware of the incident and the NRL had been informed.
