Andy Murray was diagnosed with coronavirus after testing positive, it was announced.
The tennis star tested positive for coronavirus before the Australian Open.
Murray’s participation in the Australian Open is in doubt after testing positive.
The 33-year-old Scot is scheduled to fly to Melbourne on a charter flight for the next 36 hours but remains in quarantine and isolated in London.
Murray, who is said to be in good health, is hoping to arrive in Australia at a later date and take part in the first Grand Slam of the year, which begins in Melbourne on February 8.
Murray and his team are working closely with Tournament Director Craig Tiley to find an acceptable solution.
The tournament organizers have spent several months negotiating an agreement acceptable to local and national government agencies to admit more than 1,000 tennis players and related personnel to Australia.
Players are expected to arrive in the country within the next 24 hours.
They then complete a two-week quarantine period during which they are allowed to practice from their rooms for five hours a day.
They were told that a test positive before the flight would mean they would not be allowed to travel to Australia.
