UPDATE: Billy Brownless, ex-teammate of Geelong utility Paul Brown, says the former Cat has woken up and has no recollection of the attack that left him in hospital in a serious condition.

Brownless, speaking on Triple M, said he had spoken with Brown's wife who said her husband has no recollection of the attack.

"The main thing here is that he is going to be okay," Brownless told Triple M radio.

"He's conscious, he woke up, he's got no idea what happened. He's got a fractured skull and bleeding on the brain."

FORMER Geelong player Paul Brown is in a serious condition after allegedly being king hit in Shepparton on Friday night.

Brown, 46, reportedly has bleeding on the brain and a fractured skull after allegedly being punched by another man.

The former Cat, who played 84 games including the 1994 and 1995 Grand Finals, rushed to the aid of a woman in distress, before the attacker turned on him.

He was allegedly king hit and fell backwards, hitting his head on the concrete pavement.

Brown was taken to Goulburn Valley Hospital, and later rushed to The Alfred hospital after his condition worsened.

He was in a serious but stable condition.

A 19-year-old man from Shepparton was arrested and will face court on January 11.
