FREMANTLE has confirmed the test results of a player sent for precautionary COVID-19 testing have come back negative.

The club's chief executive officer Simon Garlick revealed the results of the tests in a statement on Tuesday afternoon.

Garlick said in a statement: "Given the club's position in the community, we made a decision on Monday afternoon to take a very conservative approach even though the player did not fit all the WA Health Department criteria for COVID-19 testing."

Earlier, Dockers captain Nat Fyfe had hosed down concern about the issue, but was bracing for a wider impact on the competition.

The unnamed Docker had isolated himself as early as Tuesday afternoon after being in contact with a friend who visited China this year.

DOCKERS WAIT RESULTS Player tested for coronavirus

The player's friend, however, had reported no flu-like symptoms but had undergone a 14-day quarantine period after returning from China.

 The news broke while Fyfe was travelling from Perth to Melbourne on Monday night for the AFL's Captains Day.

Fyfe told reporters on Tuesday that it was "a non-panic situation".

"At the moment, it's in its infancy and it's just starting to affect people (but we're) remaining calm, stepping through the protocol and the doctors have told us not to stress too much.

"(We are adopting the same) standard protocols for if you were to get sick at a sporting environment, or in an environment where you're working in close proximity with other people.

"If you did have a bit of a sniffle, try and stay away, so don't get people sick – nothing different to a normal, common cold."

Fyfe discussed with the AFL's general counsel Andrew Dillon about whether it was "appropriate" for him to still attend Captains Day before he was cleared to do so.

The reigning Brownlow medallist's relaxed demeanour on the topic was evident when he joked that Brisbane skipper Dayne Zorko was "the one with a cough".

AFL chairman Richard Goyder and chief executive Gillon McLachlan updated the 15 captains in attendance on the situation, as well as Hawthorn's Tom Mitchell, Saint Seb Ross and Geelong's Mitch Duncan.

Some sporting leagues across the world are playing in front of empty stadiums, while the NBA has introduced a mandatory buffer zone between players and media outside locker rooms.

Fyfe said there was yet to be any advice about whether the virus would impact on things such as fan interaction with footballers but that he was prepared for those developments.

"I think that's sort of been the sentiment from the AFL but more broadly across Australia and the world," he said.

"No one's really got a handle on this yet but everyone's remaining pretty calm and, as I said, gradually stepping our way through it."

Other captains who spoke to AFL.com.au, including Richmond's Trent Cotchin, echoed Fyfe's sentiments, with club doctors briefing players about maintaining good hygiene and habits.

"We just need to be really careful with our hygiene and ensure we're washing our hands properly," Cotchin said.

"(Tigers CEO) Brendon Gale sent out an email with what he thinks is the best protocol.

"We just want to make sure we try and give ourselves the best opportunity to have a healthy and coronavirus-free environment for as long as possible."

Greater Western Sydney and Richmond have restricted visitor access as a precautionary measure.
