Rafael Nadal has said he felt sorry that Novak Djokovic was denied entry into Australia, but added players who are vaccinated could play in the Australian Open and the world No 1 knows the rules.
Djokovic, 34, is set to spend the weekend in detention in hotel quarantine after his appeal against his visa being cancelled was adjourned until Monday.
He was detained by officials at the border on Thursday for several hours before his visa was revoked amid a storm of protest about the decision to grant him a medical exemption from vaccination requirements to play in the Australian Open.
