Richmond duo Sydney Stack and Callum Coleman-Jones are under AFL investigation for being allegedly embroiled in a brawl outside a Gold Coast strip club, reports The Courier Mail.

It is believed that the two players were involved in an altercation on Wednesday night after being evicted from the Hollywood Showgirls on the glitter strip’s Orchid Ave.

A league spokesman told The Courier Mail: “The AFL is aware of the matter and is currently investigating”.

Police were reportedly called onto the scene as the fight broke out just meters away from the police station.

The pair breached the AFL's COVID protocols for players or coaches to attend bars, restaurants or other confined public spaces.

If found guilty, Richmond could be fined up to $100,000 and the two players will be suspended.

It marks the Tigers' second COVID breach this season, with skipper Trent Cotchin's wife Brooke attending a day spa in late July.

The $25,000 suspended from Cotchin's breach would need to be paid, as well as a further $75,000 for a second breach.

Richmond released the following statement on the matter on Twitter.

"Richmond has become aware of a breach of AFL Covid-19 protocol by two of its players, in the early hours of Friday morning," the statement reads.

"The club immediately reported the breach of protocols to the AFL, and is working with the league to investigate the matter.

"The players have been based inside the club’s player hub on the Gold Coast having already undertaken a 14-day quarantine in July. They are not part of the current quarantine hub where AFL officials, players and family members are undertaking the required 14-day quarantine period.

"The club is not in a position to comment further until the investigation is complete."
