Carr was part of Fremantle's travelling party who returned to Perth from the Gold Coast last Sunday, with the entire group forced to enter 14 days of home quarantine as per WA's current border rules.

But Carr has since been issued with a summons for three alleged breaches stemming from a police visit to his residence on Wednesday, which established he was not home.

Carr must now complete the rest of his quarantine at home with no exemptions to attend training or attend game day, including this Sunday's crunch clash with Richmond at Optus Stadium and the round 21 fixture against Brisbane.

In addition, Fremantle have stood Carr down from his coaching duties while they works with the AFL integrity department to determine any further action.

"We appreciate and understand the pressures that quarantine measures can place on individuals, however there is no excuse," Fremantle chief executive Simon Garlick said.

"And while Josh was very apologetic and remorseful, we are frustrated and disappointed by his actions and concerned about the negative impact they could have on the very positive relationships we've maintained with WA police, the State Government and the AFL throughout the course of the pandemic."

The club also revealed that first-year player Brandon Walker breached the quarantine orders by walking his dog a short distance from his home on Tuesday.

Walker advised the club later that day of his mistake.

Fremantle then contacted police, who subsequently interviewed the 18-year-old on Wednesday.

Walker will be issued with an infringement notice for a single breach of the police-issued directions orders.

"He is a young player, and while Brandon's breach was accidental, it is still disappointing and unacceptable," Garlick said.

"We've given Brandon an official warning, and he is well aware of the seriousness of the breach."
