FORMER world number one Andy Murray has reportedly tested positive for coronavirus.

Murray, from Dunblane, is now a doubt for the upcoming Australian Open.

The 33-year-old Scot was scheduled to travel in the next couple of days to Australia for the first Grand Slam event of the year.

However, he is now in quarantine and isolating at his home in London.

It is hoped that the five-time runner-up in the event will still be able to arrive in Australia ahead of the tournament, which starts on February 8 in Melbourne.

Players competing in the event must test negative before taking one of the 15 chartered flights – which have been put on by tournament organisers and are at 25 per cent capacity – to the country.

Once they have arrived, they have to pass a series of Covid tests during a 14-day quarantine in Melbourne before the tournament.
