Play at Australia Open warm-up tournaments in Melbourne has been cancelled for Thursday after a coronavirus scare, organisers announced. There will be no matches at any of the six ATP and WTA tournaments after up to 600 players and officials were told Wednesday to isolate and get tested because a worker at a hotel tested positive for Covid-19.

"There will be no matches at Melbourne Park on Thursday. An update on the schedule for Friday will be announced later today," the Australian Open`s official Twitter feed announced.
