Novak Djokovic's lawyers will appeal to a federal court in Australia within the hour
to try to overturn a Government decision, to cancel his visa for a second time over Covid rules.
If they fail, the world No.1, who isn't vaccinated could be deported.
Our correspondent Shaimaa Khalil has the latest from Melbourne.
It's a story that made headlines here in Australia and around the world.
For days, Novak Djokovic has been on the court training, and now the government has announced its decision.
The tennis star's visa has been cancelled again, and for the second time, he faces deportation from Australia.
In his statement, the country's Immigration Minister Alex Hawke said,
"Today I exercised my power to cancel the visa held by Mr Novak Djokovic on health and good order grounds, on the basis that it was in the public interest to do so."
The Prime Minister Scott Morrison said the sacrifices Australians made throughout the pandemic should be protected.
Mr Morrison's government has faced heavy criticism for allowing the unvaccinated player into Australia in the first place,
while the country struggled with a spike in Covid-19 case numbers.
The world No.1 is still fighting to defend his title here.
Whether or not he'll be able to play, the Australian Open will take place under the shadow of a controversy that has gone way beyond tennis.
