Jannik Sinner and Novak Djokovic withdraw from the ATP Montreal Masters, organizers Tennis Canada announced. The event runs Aug. 1–13 and is an ATP Masters 1000 tournament that serves as a key lead-up stop to the US Open. Sinner, currently world No. 1, and Djokovic, a 24-time Grand Slam champion, both pull out of the next month’s tournament as part of a busy competitive schedule. The announcements follow their deep runs in recent Grand Slam play at Wimbledon. Sinner wins the men’s title at Wimbledon, while Djokovic reaches the semifinals. The reports do not cite specific reasons for the withdrawals, and no replacement players are mentioned in the provided coverage. The change affects the draw for Montreal, where both players were expected to compete given their standings and recent results. Tennis Canada’s statement is the source of the confirmation for both athletes’ absence from the Masters event.
