Djokovic was denied being able to play in the Australian Open for being unvaccinated against COVID-19. He tried to enter Australia with a visa and exemption, Yahoo Sports reported.

He had been cleared originally, but there was not enough information about his status so he was detained. Appeals were denied and he was deported before Day One of the tournament.

Djokovic also came under fire for attending public events after testing positive for COVID-19, ESPN reported.

If he had been permitted to compete, he could have gone for his 21st Grand Slam victory, breaking a tie for the most men’s titles of all-time.

It is currently a three-way tie between Djokovic, Roger Federer and Rafael Nadal.

Now Djokovic could miss the French Open after the French parliament on Sunday approved a law that requires anyone who goes to restaurants, sporting events and other venues to be vaccinated against the coronavirus. Before the new law, people who were unvaccinated could enter establishments with a negative test.

The French Open and the French sports ministry said there will be no exemptions for unvaccinated players, Reuters reported.

The law stands until further notice but the sports ministry said the regulations could change by the time the French Open happens in May.

Djokovic is the defending champion at Wimbledon, and England currently allows exceptions for visiting athletes. The U.S. Tennis Association, which runs the US Open, will abide by the federal government’s vaccination rules, ESPN reported.
