Canadian tennis star Denis Shapovalov has announced he has tested positive for Covid-19 after arriving in Sydney ahead of the Australian Open.
Former world No 10 Shapovalov played last week at the World Tennis Championship exhibition event in Abu Dhabi, where he beat 20-times major winner Rafa Nadal in the third-place playoff match.
Nadal, Olympic champion Belinda Bencic and Tunisian Ons Jabeur all tested positive for the virus after playing the tournament.
Shapovalov said he is experiencing minor symptoms.
All players have to return negative tests 72 hours before flying to Australia.
They also have to undergo testing upon landing in Australia and, while waiting for the test results, have to remain in isolation.
Djokovic has declined to disclose whether he is vaccinated, citing privacy concerns.
The Australian Open chief, Craig Tiley, said on Wednesday he is still uncertain whether Djokovic will be playing at the Melbourne Park major.
Tiley has said all players and staff at the Australian Open would be vaccinated or have a medical exemption granted by an independent panel of experts.
Australian Open organisers said Raonic pulled out of the first grand slam of 2022 as he continues his recovery from a heel injury, organisers say.
Raonic suffered a thigh injury in March and returned to the tour after a three-month gap. But his 2021 season was cut short due to another heel issue following his first-round loss at the Atlanta Open in July.
The Canadian, who has currently slipped to 70th, is the latest to be ruled out of the Australian Open, with Roger Federer, Stan Wawrinka, Jennifer Brady, Karolína Plí¨ková, Karolína Muchová, Serena Williams and Bianca Andreescu also ruled out with injuries.
