ADELAIDE players in quarantine are now training as individuals so as to take out any possibility of further breaches of coronavirus training protocols.

The South Australian club has been cautioned by police and is still waiting to learn details of its penalty from the AFL after a group of players breached the League's rules which ban training in groups of more than two players.

Sixteen Adelaide players and assistant coach Ben Hart are at a golf resort in the Barossa Valley to serve a 14-day quarantine period after returning to SA from interstate.

Senior coach Matthew Nicks confirmed a group of eight players kicked balls together after a running session on Thursday.

But the Crows have strenuously denied they deliberately set out to circumvent coronavirus protocols.

"We understand the ramifications of this and it's affected the entire industry and we're sorry for that," Nicks told Fox Footy on Saturday.

"We take full responsibility but I just feel for my young players, who at the moment are still up at the facility.

"They're now training as individuals to take out any risk, but it's a really tough time for those guys."

The AFL Integrity Unit had hoped to conclude its investigation into the breach by close of business on Friday, but it has now spilled into the weekend.

Nicks said the Crows were not involved in a negotiation with the AFL over their penalty.

There is the prospect of a large financial sanction for the club and possible suspensions for the players involved.

"We just have to await their feedback on that," Nicks said.

Nicks said he had been contacted by rival senior coaches, who have offered their support to the first-year Crows coach.

Port Adelaide chairman David Koch confirmed his club's players that had returned to SA from interstate were in quarantine isolation at their regular homes in Adelaide.

"I personally couldn't justify putting a whole bunch of players up in a resort for two weeks when we had staff not being paid (and) they've got home accommodation for themselves," Koch told Fox Footy on Saturday.

"For me, it was very simple and the quarantine laws are pretty straightforward in South Australia."
