Novak Djokovic's inability to play at certain Grand Slam tournaments could continue in 2023.
The Serbian star missed both the Australian Open and US Open this year due to his decision not to get vaccinated against COVID-19.
Djokovic was dramatically deported out of Australia in January after previously being given a medical exemption to enter the country.
His ultimate absence allowed Rafael Nadal to edge past both Djokovic and Roger Federer for most Grand Slam titles won.

While Australia continues to ease their COVID-19 rules, Australian Open tournament director Craig Tiley admitted Djokovic's participation in 2023 remains up in the air with the government required to waive his ban.
"It's not a matter we can lobby on," Tiley said.
"Novak and the federal government need to work out the situation and then we'll follow any instruction after that.
"It's a matter that definitely stays between the two of them and then depending on the outcome of that we would welcome him to the Australian Open."
In September, Djokovic said he was hopeful he'd be able to play at the 2023 Australian Open as he stood by his decision not to get vaccinated and the consequences that have come with it.
“It’s really not in my hands right now. So I’m hoping I will get some positive news," Djokovic said.
“I don’t have any regrets. I mean, I do feel sad that I wasn’t able to play, but that was a decision that I made and I knew what the consequences would be. So I accepted them and that’s it.
“I’m not used to making, obviously in the last 15-20 years, longer breaks between the tournaments, but it is what it is."
While Djokovic may not be allowed to compete at the Australian Open in 2023, Tiley confirmed Russian and Belarusian players can player under certain conditions.
"They cannot participate in any activity such as the anthem of Russia and they have to play as independent players under a neutral name," said Tiley.
The 2023 Australian Open is expected to get underway on January 16 in Melbourne.
