Novak Djokovic withdrew from the upcoming hard-court tournament in Montreal on Thursday because he is not vaccinated against Covid-19 and is therefore not allowed to enter Canada. By the same reason, as things stand now, he also will not be able to compete in the US Open later this month. Djokovic, a 35-year-old from Serbia, has said he will not get the shots, even if that means he cannot go to certain tournaments. He missed the Australian Open in January after being deported from that country and needed to sit out two events in the United States earlier this year. He did play in the French Open, where he lost in the quarter finals to Rafael Nadal, and at Wimbledon, which Djokovic won last month for his 21st grand slam title – one behind the men’s record held by Nadal. Unvaccinated foreign citizens cannot go to Canada or the US, so Djokovic pulled out of Montreal a day before the draw is expected to take place for the tournament and is expected to have to sit out the US Open, which starts in New York on August 29. Last weekend, Djokovic posted on social media that he was holding out hope of getting the chance to play in the US Open, writing: “I am preparing as if I will be allowed to compete, while I await to hear if there is any room for me to travel to US. Fingers crossed!” After beating Nick Kyrgios in the Wimbledon final on July 10, Djokovic said he “would love” to participate in the last grand slam tournament of the year at Flushing Meadows, but also acknowledged, “I’m not planning to get vaccinated.” Djokovic is a three-time champion at the US Open. His loss to Daniil Medvedev in last year’s final there prevented Djokovic from becoming the first man since Rod Laver in 1969 to win a calendar-year grand slam. Oscar Otte also withdrew from Montreal on Thursday; Kyrgios and Benjamin Bonzi moved into the bracket. Four wild-card berths went to three-time major champion Andy Murray, David Goffin, Vasek Pospisil and Alexis Galarneau. Nadal, who pulled out of Wimbledon before the semi-finals because of a torn abdominal muscle, is still expected to play in Montreal.
