The father of West Coast Eagles star Brent Staker has described Sydney Swans' Barry Hall as "a weak mongrel" for king-hitting his son during an AFL match in Sydney.

Alan Staker, speaking from his Broken Hill home, said he was waiting to see whether the AFL stood by its resolution to deal harshly with players who attacked the heads of their rivals.

Staker was knocked unconscious when he was punched in the jaw in the first quarter of Saturday night's game at ANZ Stadium in Sydney.

Hall has apologised for the incident and says he will accept any punishment coming to him.

Alan Staker, a veteran of 300 games in the far western NSW town, said he would be outraged if Hall was suspended for only "a few" matches.

"I thought it was pretty weak ... if it was a fight fair enough, but not to be king hit when there's nothing in it and you're not expecting it," he told ABC radio in Perth.

"My disappointment is in the AFL ... they spruik about players not being allowed to go anywhere near the head now and penalising them if they do.

"So let's see what they do. He deserves a fair sentence for a fairly weak act."

Asked how he felt about Hall, Staker said: "He's a weak mongrel."

Brent Staker's mother Rosemary said she was not watching the match and felt "sick in the stomach" when a friend told her what had happened.

"Brent remembers absolutely nothing," she said.

"He said from the time he got hit to the time he realised he was on the bench he can't recall a thing.

"The doctors stayed with him all the time and also back at the motel and checked him right through the night.

"They're going to do x-rays in Perth and take it from there."

Rosemary Staker said the AFL must use the incident to set an example and curb on-field violence, as "the parents of hundreds of kids won't want them to play football because of this".

"For someone who's been playing as long as he (Hall) has, and who's supposed to be one of the heroes of the game, he is pretty weak," she said.

"No young lad out there trying to win games for his club or with his teammates deserves this."
