Nick Kyrgios was hoping to make his return to the court for the first time since September on Monday, but a positive covid-19 test meant he had to pull out of the Sydney Tennis Classic.
The former world No.13 had been scheduled to face the tournament's seventh seed, Italian Fabio Fognini, at Ken Rosewall Arena in the evening, but pulled out just hours before it's start.
It was a decision that raised eyebrows, with the match seemingly Kyrgios' last chance to warm-up before the Australian Open starts on January 17. However, the 26-year-old has since stated that he had no choice after testing positive with the virus.
On Monday morning, Kyrgios took to Instagram to explain his absence.
"Hey everyone, I just want to be open and transparent with everyone, the reason I have had to pull out of Sydney is because I tested positive for Covid.
"I am feeling healthy at the moment with no symptoms. I wish everyone all the best and to stay safe where you can. If all goes well I will see you at the Australian Open."
The cancellation comes just a week after Kygrios pulled out of the Melbourne Summer Set, with the world No.114 stating an illness had sparked his asthma.
"Whatever I've got at the moment is really wearing me down, kind of been bedridden for the last couple of days," Kyrgios said at the time. "Really struggling to breathe, my asthma has been acting up like crazy.
"I have had several covid-19 tests over the last few days, which all came back negative. I don't feel 100% so I need to take this week to be ready for Sydney."
Now, with just one week to go until the first Grand Slam of 2022 starts, Kyrgios's chances of returning in time look slim.
