Tokyo Olympics: Australia's Alex de Minaur tests positive for COVID-19, forced to withdraw from Olympics

Australian tennis star Alex de Minaur has been forced to withdraw from the Tokyo Olympics, after testing positive for COVID-19.

The 22-year-old was yet to travel to Tokyo, but will now remain in Australia as another withdrawal from the Olympic tennis tournament.

Australia's No.1 ranked men's player, de Minaur was due to compete in Tokyo's singles tournament, as well as the doubles with partner John Peers.

"We are very disappointed for Alex and he is shattered at not being able to come," Australia's Chef de Mission Ian Chesterman says.

"It has been his dream to represent Australia at the Olympic Games since he was a child, but he sent his best wishes for the team."

No other Australian players have tested positive for COVID-19 as of yet. 

De Minaur initially tested negative when leaving the Wimbledon bubble on July 2, before departing England for Spain.

But according to Fox Sports, de Minaur tested positive on July 10, ahead of departing for Tokyo.

Fellow mens stars Stanislas Wawrinka, Dominic Thiem and Nick Kyrgios will also sit out of the tournament.

In the women's draw, Simona Halep, Naomi Osaka and Serena Williams have withdrawn, along with Britain's Johanna Konta. 

De Minaur's withdrawal comes after a COVID scare in the Australian basketball camp, following USA's Bradley Beal also tested positive, following the Boomers' 91-83 victory on Tuesday (NZ time).

However, all of the Australian basketball players and officials have returned negative tests.
