Wimbledon champion Novak Djokovic has been told to "roll up his sleeves and receive the vaccine" as the Serbian faces missing the US Open.
Djokovic has been outspoken about not wanting to get vaccinated against Covid-19, with his stance forcing him to miss this year's Australian Open. And he also looks set to miss the US Open, with America's Covid restrictions requiring foreigners to be vaccinated in order to enter the country.
Canada also have similar restrictions in place, meaning Djokovic is also likely to miss the Canadian Open in Montreal. The tournament takes place shortly before the US Open and typically forms a key part of a player's preparation for Flushing Meadows.
