Djokovic to miss ATP Cup in Sydney: Report

Djokovic has declined to disclose whether he is vaccinated, citing privacy concerns.

Serbia have been drawn in Group A - along with Norway, Chile and Spain - at the ATP Cup, which is scheduled for January 1-9, before the Australian Open begins on January 17.

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.

Those requirements have prevented Djokovic from confirming whether he will bid for a men's record 21st grand slam title and a 10th Australian Open crown.
