NEW YORK — Novak Djokovic will not play in the U.S. Open, as expected, because he is not vaccinated against Covid-19 and thus is not allowed to travel to the United States. Djokovic announced his withdrawal from the year’s last Grand Slam tournament on Twitter on Thursday, hours before the draw for the event was revealed.

“Sadly, I will not be able to travel to NY this time for US Open,” Djokovic wrote, wishing luck to his fellow players, and said he would “keep in good shape and positive spirit and wait for an opportunity to compete again.” Play is scheduled to begin at Flushing Meadows on Monday. Djokovic is a 35-year-old from Serbia who owns 21 major championships, one behind Rafael Nadal for the men’s record.

Three of Djokovic’s Slam trophies came at the U.S. Open, in 2011, 2015 and 2018. He also was the runner-up there a half-dozen times, including last season, when his pursuit of the first calendar-year Grand Slam in men’s tennis since 1969 ended with a loss in the final to Daniil Medvedev. Foreign citizens who have not been vaccinated against Covid are currently unable to enter the U.S or Canada, and Djokovic has said he won’t get the shots, even if that prevents him from playing in certain tournaments.
