Richmond has confirmed two of its players have been arrested over an alleged altercation on the Gold Coast.
Sydney Stack and Callum Coleman-Jones were arrested at 3:30am on Friday morning.
Queensland Police said two men, aged 20 and 21, were arrested after a “physical altercation”.
Both players suffered facial injuries and were issued with penalty infringement notices for violent behaviour.
Police said investigations were continuing into the matter.
Richmond said it “immediately reported the breach of protocols to the AFL”, and is investigating the incident.
It said both players had been based in the Gold Coast hub since July but were not currently part of the quarantine hub.
AFL players are, however, required to stay inside their “bubbles” to minimise the risk of contracting coronavirus, excluding them from visiting local bars or restaurants.
Richmond will likely be fined, with the players almost certainly banned for the rest of the season.
Sydney Swans player Elijah Taylor was suspended for breaching protocols in Perth in July, with the Swans fined $50,000, half of which was suspended.
It is Richmond’s second COVID breach of the season after captain Trent Cotchin’s wife broke biosecurity protocols by travelling to a day spa on the Gold Coast in July.
The incident comes two days after Queensland was announced as host of the AFL grand final for the first time.
Queensland Opposition Leader Deb Frecklington said in a statement that the players should be sent back to Victoria after their “reckless behaviour” put the “lives and livelihoods of Queenslanders at risk”.
Richmond beat Fremantle on the Gold Coast on Wednesday at Carrara to move into the top four, having won its last four matches.
It next takes on fellow finals aspirants Geelong on Friday, September 11, also at Carrara.
