Novak Djokovic pulled out of next week's hard-court tournament Cincinnati Masters as the star tennis player has not received COVID-19 Vaccination and is not allowed to travel to the United States.
Djokovic is also not expected to be able to enter the U.S. Open, the year's last Grand Slam tournament, which begins in New York on August 29.
Djokovic is a 35-year-old from Serbia who owns 21 major championships, one behind Rafael Nadal for the men's record. Djokovic has said he won't get vaccinated against the illness caused by the coronavirus, even if that prevents him from playing in certain tournaments.
