Amid doubts over his participation at the first Grand Slam of the year, Australian Open, World number 1 Novak Djokovic has withdrawn from the 2022 ATP Cup.
Djokovic's withdrawal from the men's teams event in Sydney comes amid mounting speculation over the 34-year-old's Covid-19 vaccination status, with the 20-time Grand Slam champion has refused to reveal publicly whether he has been jabbed.
All players and staff at the Australian Open must be vaccinated or have a medical exemption granted by an independent panel of experts.
The Australian Open starts in Melbourne on 17th January, and players have started to arrive in the country for warm-up events over the coming week. In a statement, Tennis Australia said the Serbian team at the ATP Cup would be led by world number 33 Dusan Lajovic.
