Former world number one Andy Murray has tested positive for the coronavirus.
The 33-year-old Brit had been preparing for the year’s first Grand Slam, the Australian Open, and was due to travel on one of the 18 charter flights laid on by tournament organisers.
Instead he remains in quarantine and isolating at home in London.
Players must test negative before taking one of the 15 chartered flights – which have been put on by tournament organisers and will operate at 25% capacity – to Australia.
Once they have arrived, they will have to pass a series of Covid tests during a 14-day quarantine in Melbourne before the Grand Slam.
Murray, who is said to be in good health, remains hopeful he will be able to arrive in Australia at a later date and still participate in the tournament which begins on February 8.
Murray is a three-time Grand Slam winner and five-time finalist at the Melbourne event.
