The organisers of the party after which Dylan Napa forward Sydney Roosters  was alleged to have been knocked out have distanced themselves from the incident.

Dylan was struck with a fire poker by another party-goer on Sydney's northern beaches on Sunday morning having come to the aid of a woman, according to News Corp Australia.

The Sydney's 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.

Host Theo Chambers, a mortgage broker and the son of Chambers Cellars owner Steven Chambers, has moved to distance the Palmbu event from the incident.

"I would like to particularly stress that the apparent break and entry and assault which took place at my premises the day after the charity event, happened a considerable time after the event had been closed and all attendees had been cleared from the premises by licenced security," Theo Chambers said in a statement provided to AAP by his lawyers.

"I had also left and locked up the property for the evening. There is no information suggesting that the charity event and the break and entry and assault were in any way connected.
"As more information comes to hand, I will consider pressing charges and any other claims I may have against those responsible."

Chambers said the event raised more than $13,000 for charity.

A police spokeswoman told AAP emergency services were called to the Bynya Road premises around 3am on Sunday following reports of a fight.

"Two men, aged 33 and 24, and a 26-year-old woman, were treated at the scene by NSW ambulance paramedics for minor injuries," the spokeswoman said.

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.
The 24-year-old Napa was last week selected in the Queensland emerging representative squad.
