The tournament director of the Canadian Open says changes need to be made to the "demanding schedule" of players after Jannik Sinner and Novak Djokovic pulled out of the Masters 1000 event. Carlos Alcaraz will also be absent from the Canadian Open as he continues his recovery from a wrist injury that has kept him out since April. "We are obviously very disappointed that Jannik and Novak won't be joining us in Montreal this year, especially after they also withdrew from last year's tournament in Toronto," said the Canadian Open's tournament director Valerie Tetreault. "Masters 1000 events are among the flagship tournaments on the tour, and fans rightfully expect to see the world's best compete. The Canadian Open takes place before the Cincinnati Open, which is also a Masters 1000 event, and prior to the start of the US Open - the final Grand Slam of the year - on 30 August.
