Novak Djokovic, Jannik Sinner, and Jack Draper have all withdrawn from the National Bank Open in Toronto, citing injuries. Djokovic and Sinner are facing concerns after their recent performances, while Draper is taking time off to recover from an arm injury sustained at Wimbledon. The withdrawals from these top-ranked players have raised questions about their fitness ahead of the upcoming US Open, with Draper specifically targeting a return in time for the event. This development not only impacts their personal schedules but also opens up opportunities for other competitors in the ATP Tour.
