World number one Jannik Sinner withdraws from the upcoming Shanghai Masters because of an ongoing right knee injury, delaying his return to competition. Multiple outlets report that he has not played since winning Wimbledon in July.

According to reports, Sinner announces the decision via Instagram, saying he is unable to compete as he had hoped. Sources also note that his absence has extended through parts of the hard-court season, including the US Open and events in Beijing, with outlets emphasizing that the knee issue continues to linger.

While most coverage focuses on the injury and missed tournaments, one outlet adds context about potential implications for his world No. 1 ranking. The Independent reports that Sinner could lose his top ranking to Alexander Zverev depending on ATP outcomes during his absence, but other sources primarily concentrate on the withdrawal and recovery timeline.
