France is tightening its vaccination rules in a manner that could put Novak Djokovic in danger of missing the French Open.

From February 15, any individual who isn’t vaccinated against the coronavirus should show evidence they tested positive for COVID-19 within the previous four months – down from the current six-month window – to enter sports venues in France.

Djokovic, who isn’t vaccinated, said he tested positive in mid-December. Under the current guidelines with a six-month window, he could play in the French Open, what starts May 22 But if the new requirements stay in force until then, they are probably going to rule him out unless he gets vaccinated or tests positive again inside four months of the beginning of the clay-court Grand Slam.

French Open organizers have recently said it’s too soon to remark since virus restrictions can change between now and May relying upon the circumstance.

Djokovic was allowed an exception to Australia’s severe vaccination rules by two medical panels and the tournament organizer to play in the Australian Open in light of documents he supplied showing he had recently had COVID-19. He got a visa to enter the country through an automated process. But upon arrival, border officials said the exclusion was not valid and moved to deport him.

Eventually, Australian authorities revoked Djokovic’s visa, saying his presence could stir up anti-vaccine sentiment and that showing him out was important to keep Australians safe. He was deported a day prior to the tournament got underway in Melbourne.
