"I'm very disappointed to not be able to play in the coming weeks after training hard in the off-season and knowing Tennis Australia and the tours did so much to make these events happen," the 25-year-old tweeted https://twitter.com/Madison_Keys/status/1349717917064163335. Earlier, Britain's former world number one Andy Murray tested positive for the virus, putting his Australian Open participation in doubt.
