Former world No. 1 Andy Murray said he was "gutted" after deciding to withdraw from next month's Australian Open following a positive test for COVID-19 earlier this month.

The 33-year-old Murray, a wildcard, confirmed last Thursday that he had tested positive for the virus and was in self-isolation at his home near London.

That meant he was unable to take one of the charter flights provided by Australian Open organizers, leaving him in a race to arrive in enough time to complete a mandatory 14-day quarantine period.
