Novak Djokovic’s participation in the Australian Open in January is in doubt after officials confirmed all players must be vaccinated in order to compete in the tournament.

Djokovic, a nine-time winner in Melbourne, has repeatedly refused to disclose his vaccination status and intimated he would not play if the vaccine ruling was enforced.
