Play on Thursday at the pre-Australian Open events at Melbourne Park has been cancelled by tournament officials after a positive COVID-19 test at a player hotel.
A decision concerning the Friday schedule at the ATP Cup, and other ATP and WTA events will be made later.
“Health Authorities have advised us that a Hotel Quarantine worker has tested positive for COVID-19,” an official statement read.
“Those associated with the AO who quarantined at the hotel now need to be tested and isolate until they receive a negative test result.
“We will work with everyone involved to facilitate testing as quickly as possible.
“There will be no matches at Melbourne Park on Thursday 4 February 2021. An update on the schedule for Friday will be announced later today.”
Up to 500-600 people associated with the tennis – including many players who are using the five-star Grand Hyatt hotel as their base – will be expected to quarantine until providing a negative test.
Reports indicate that the positive case is a 26-year-old man who worked security at the hotel on January 29 (last Friday) and later tested positive.
His weekend movements around his home area in outer Melbourne are being contract traced.
With a tight schedule until Monday’s start of the Open – already delayed three weeks by virus safety protocols – the Grand Slam’s future apparently remains an open question.
