Top-ranked Sinner withdraws from US Open due to knee injury

Jannik Sinner, the world's top-ranked tennis player, has withdrawn from the US Open due to a knee injury, marking a significant absence for the five-time Grand Slam champion. The Italian's withdrawal comes after an extended spell on the sidelines following his victory at Wimbledon earlier this summer.

Sinner's injury concerns were first evident when he opted out of hard-court preparation tournaments in Cincinnati and Montreal, events typically used by elite players to build momentum ahead of the final major of the season. The decision to miss the US Open underscores the seriousness of his physical condition as the season enters its crucial final stages.

The 23-year-old's absence represents a notable blow to the US Open field, removing one of the tournament's strongest contenders from competition. His withdrawal also impacts the men's rankings race heading into the remainder of the professional calendar.

Sinner's team has not provided a detailed timeline for his return to competitive play. The injury setback will be closely monitored by his camp as they assess his readiness for future tournaments.
