Novak Djokovic was detained by Australian border authorities on Saturday morning, as per a court-ordered arrangement decided Friday heard by CNN in open court.
The move follows a decision by Australia's immigration minister Alex Hawke to revoke the tennis star's visa on Friday after days of deliberation about whether to eject the 34-year-old Serbian from the country.
Djokovic is accused of providing false information on his Australian visa declaration, specifically that he hadn't traveled in the 14 days before his arrival in the country.
Djokovic's lawyers are appealing the decision, and his case to stay in Australia will be heard on Saturday before the country's Federal Court following an emergency hearing before Judge Anthony Kelly in the Federal Circuit and Family Court on Friday.
If Djokovic's bid fails, he could be deported.
