Madison Keys, the World number 16, has confirmed she has tested positive for coronavirus just days before she was due to fly to the Australian Open.
The announcement from Keys, made on twitter, follows news that Britain's Andy Murray also tested positive and will delay his flight to Melbourne.
While Murray is still keeping his hopes alive of an Australian Open comeback, Keys appeared a little more uncertain of whether the first Grand Slam of the season is achievable.
American Keys, who is a former semi-finalist in Melbourne, tweeted her disappointment about the news and informed fans she will now begin a period of self-isolation.
The news comes just as pictures emerge of the first players arriving in Melbourne for the first Grand Slam of the year.
The first of 15 charter flights carrying tennis players and officials for the tournament, starting on February 8, landed at Tullamarine’s Melbourne Jet Base earlier today.
The Doha flight arrivals were greeted by airport staff and biosecurity officials wearing personal protective equipment including masks and face shields, before being whisked away to hotel quarantine.
More private jets from Doha, Abu Dhabi, Los Angeles, Singapore and Dubai will land in the Victorian capital over the next 36 hours.
