Andy Murray has tested positive for coronavirus just weeks before he is due to play in the Australian Open, Sky News understands.
The former world number one was due to travel to Australia on one of the 18 charter flights laid on by tournament organisers but is still isolating at home.
Sir Andy is understood to be in good health despite the infection.
The tournament doesn’t begin until 8 February and Murray is thought to be hoping to travel at a later date.
Tournament organisers have spent months negotiating with authorities to allow more than 1,000 players and personnel into Australia.
Players are due to begin arriving in the country within the next 24 hours.
They will then complete a two-week period of quarantine, during which they are allowed out of their rooms to practise for five hours a day.
They were told that a positive test prior to flying would mean they were not allowed to travel.
