Three COVID-19 positive cases were found across two Australian Open charter flights from Los Angeles and Abu Dhabi on Friday morning.
As a result, more than 120 officials, coaches and tournament people, including 47 players, have been deemed close contacts and mandated to 14 days of hotel quarantine.
Greece’s Maria Sakkari is within the unlucky cohort, unable to leave their rooms to train.
Sakkari arrived onboard the Abu Dhabi charter flight to Melbourne, where Canadian Sylvain Bruneau, the coach of 2019 US Open champion Bianca Andreescu, tested positive.
Mr Bruneau said he was “deeply sorry” about his positive result and that he hoped “any further disruption is kept to a minimum.”
The apologetic statement posted on Twitter continues as follows:
“I also respected and followed all COVID protocols and guidelines while in the Middle East. I have no idea how I might have contracted this virus.
“I am extremely saddened and sorry for the consequences now on everyone’s shoulders sharing my flight.
“The rest of my team is negative, and I sincerely hope that any further disruption is kept to a minimum.”
The other two coronavirus infections on the flight from the US are also of non-players: a flight crew member and a tournament participant.
Elite players in Sakkari’s flight include Svetlana Kuznetsova, Ons Jabeur, Belinda Bencic and Marta Kostyuk.
Same as their colleagues who arrived with the LA flight they will remain into strict isolation, unable to train during the two weeks ahead of the tournament, starting on 8 February.
Exercise equipment will be made available to players in their hotel rooms to substitute for outside training, while Tennis Australia CEO, Craig Tiley said that scheduling of the games will be reviewed.
“There is a difficulty because there are events leading in and those players to be ready to play those events it is going to be extremely difficult.
We need to what we can do as best as we can for those players by providing exercise equipment in their rooms.
“We will do that over the course of today and then keep monitoring the situation,” Mr Tiley said.
