Jannik Sinner has withdrawn from the China Open in Beijing, marking his fourth tournament absence. The world No. 1 in the ATP rankings will miss the event running from September 30 to October 6, following a right knee injury sustained in late July.
A Growing Competitive Hiatus
The latest withdrawal extends a layoff that began after Sinner secured his last match victory at Wimbledon on July 12. The 25-year-old has already missed a sequence of major hard-court events, including Montreal, Cincinnati, and the US Open.
Projected Return and Recovery Risks
According to an analysis published by Adriano Panatta in Corriere della Sera, Sinner’s absence could stretch further. He might be sidelined until the Shanghai Masters on October 7 or the Vienna Open on October 24, resulting in a total layoff of three to three and a half months.
The right knee injury occurred during training. Panatta emphasized that rushing the recovery process carries substantial risks for the top-ranked player.
“If he forces his return schedule, he risks much more than waiting patiently for the limb to regain full functionality and for the pain to completely disappear,” Panatta stated in Corriere della Sera.
Modern Equipment and Tour Demands
Discussing the broader physical toll on professional athletes, Panatta pointed to modern tennis racquets as a primary driver behind a reported 110 percent increase in player injuries compared to the early 2000s.

The 1976 Rome and Paris champion argued that the combination of two-week tournament formats, power-based playing styles, and racquets engineered for constant acceleration places severe stress on players’ bodies.
The Future of Elite Scheduling
“Muscles, wrists, backs, shoulders, and knees naturally,” suffer under these conditions, Panatta wrote in Corriere della Sera, adding that the physical demands affect top competitors across the tour.
He noted that young champions like Sinner and Carlos Alcaraz recognize the necessity of scheduling planned breaks, signaling that players may need to adapt their playing styles to cope with tour demands.
