Jannik Sinner has withdrawn from the Shanghai Masters because his knee problem continues to affect him, according to Al Jazeera. The same source identifies the Italian tennis player as the world No. 1.

Al Jazeera reported the withdrawal on October 3, 2026, linking it to the ongoing knee problem. The news therefore concerns Sinner’s participation in the Shanghai Masters, with no further official details about his condition.

According to the outlet’s summary, Sinner has not taken to the court since his victory at Wimbledon in July. His withdrawal from the Shanghai Masters therefore adds to an absence that was already ongoing, as described by the source.

Al Jazeera also reports that the tennis player missed the US Open and the ATP 500 event taking place in Beijing during this period. However, the source does not independently clarify the precise connection between the knee injury and each of the two absences.

Neither the severity of the injury nor a date for his return to competition is given. In the material considered, Al Jazeera does not provide a forecast for Sinner’s recovery time.

The report provided contains no official statement from Sinner, the tournament organizers or the ATP. The episode therefore remains supported by the account of a single news organization.

For now, based on the information reported by Al Jazeera, the central fact is the world No. 1’s latest withdrawal from a tournament and the continuation of his absence since Wimbledon. The development of the knee problem and the timing of his return remain unclear.
