Fremantle AFL defender Luke Ryan says his coronavirus protocol breach in April was a "dumb mistake" that won't happen again.
Ryan and his teammates Michael Frederick and Jason Carter were caught flouting the WA government's COVID-19 restrictions when Instagram footage emerged of them at a house party.
At a time when social gatherings were capped at two people, the event featured seven.
The Dockers trio were later cleared by WA Police but Ryan and Carter were fined $3000 ($2000 suspended) by Fremantle.
Ryan didn't want to go into specifics about how the party situation came about when quizzed about it on Wednesday but he said he learned from his error.
"It was a dumb mistake but I won't do it ever again," he said.
"I'd rather not talk about it. It was a mistake, I've put it behind me and moved on."
Ryan is focused on helping Fremantle turn around their 0-3 start to the season.
The Dockers face in-form Gold Coast at Metricon Stadium on Saturday night and they could be boosted by the return of ruckman Sean Darcy (knee) and defender Stephen Hill (calf).
Fremantle are considering handing a debut to 19-year-old midfielder Caleb Serong.
"He reminds me of Lachie Neale," Ryan said of the No.8 pick from last season's national draft.
"He's so clean and strong, and he always wants to learn.
"It looks like he's played 100 games already. He's just so smart and clean.
"I wouldn't be surprised if he debuts this week."
Fremantle struggled in the wet conditions in Sunday's 29-point loss to Port Adelaide, despite the Dockers' best efforts at training to get accustomed to a slippery ball.
"We've been using water down at training and putting soap on it and all that stuff," Ryan said.
"We handled it pretty well in the first quarter, it's just when the rain came down we didn't adapt to it."
