Jannik Sinner, Ben Shelton among players withdrawing from ATP tournaments

Jannik Sinner and Ben Shelton are among four players who have withdrawn from the ATP Beijing and Tokyo tournaments, respectively. Sinner, the defending champion, is sidelined due to a knee injury and has not played since winning Wimbledon. Shelton, recently a US Open finalist, is taking time off after an intensive schedule. Both tournaments are set to feature alternate players as a result of these withdrawals. Quentin Halys and Sebastian Baez will replace Sinner and Raphael Collignon in Beijing, while Alex Michelsen and Luca Van Assche will fill Shelton's and Joao Fonseca's spots in Tokyo.
