Andy Murray takes wild card for next tournament as Briton aims to be seeded at US Open

Seven months after his fiasco with the Australian Open, Djokovic's vaccination status is once again an obstacle, the Serb not being able to enter Canada. That appears to be just the start for the world No. 1, however, as he is also set to miss the US Open next month, with his entry to the United States expected to be denied as he has not been trapped with the virus.

Nadal, meanwhile, will miss the Rogers Cup due to ongoing fitness issues, having been forced to withdraw from his Wimbledon semi-final with Nick Kyrgios last month. Confirming his withdrawal, he said: “We have decided not to travel to Montreal and to continue training without forcing anything. I sincerely thank the tournament director, Eugène, and his entire team for the understanding and support they have always shown me. Today was no exception."
