Alcaraz latest star to bow out of Toronto's NBOCarlos Alcaraz has withdrawn from the National Bank Open, depriving the men's tennis tournament in Toronto of yet another star player.
Alcaraz said in a statement issued by tournament organizers Monday that the tournament comes too soon after his appearance in the Wimbledon final on July 13.
The world No. 2 announced his withdrawal the day after top-ranked Jannik Sinner, 24-time Grand Slam champion Novak Djokovic and world No. 5 Jack Draper pulled out of the ATP Masters-level hardcourt event.
Sinner, who defeated Alcaraz in the Wimbledon final, said he injured his elbow in a fall at the All England Club. He won his first Masters title in Toronto in 2023.
Djokovic blamed a groin injury for his withdrawal from an event he has won four times, while Draper is recovering from a forearm injury.
The women's NBO tournament in Montreal has also had high-profile players withdraw, including world No. 1 Aryna Sabalenka.
The NBO tournaments start Saturday with one-day qualifying events.
