World number one Sinner withdraws from Shanghai Masters as knee recovery drags on into 2026
Jannik Sinner will play no part in the Asian swing of the tennis calendar in 2026. The world number one announced on social media that he will miss next week's Rolex Shanghai Masters, extending an absence from competition that has now reached nearly three months.
"Unfortunately I won't be able to play at the Rolex Shanghai Masters this year as I had hoped," Sinner wrote. "I've always loved playing in front of the fans in Shanghai and I'm really sorry not to be able to do so next week."
Sinner has not played since July 12, 2026, when he defeated Alexander Zverev in the Wimbledon final. An inflammation of a tendon outside the right knee joint has kept him sidelined through the summer hard-court season in North America and now the autumn swing through China.
Medical consultation in Lyon
The South Tyrol native travelled to France for a specialist consultation between October 2 and 3, 2026. Dr. Bertrand Sonnery-Cottet examined Sinner at the Santy Orthopedic Centre in Lyon, a facility known for treating knee injuries in elite athletes.
The French surgeon recommended continuing with conservative therapy rather than surgery. Sinner has already undergone targeted treatment including shockwave therapy at JMedical in Turin, the medical centre linked to Juventus, and argon laser therapy designed to promote tissue recovery and allow a gradual increase in training intensity.
No date has been set for his return to competitive play.
Ranking battle intensifies
Sinner's prolonged absence opens the door for Alexander Zverev to overtake him at the top of the ATP rankings. Sinner is guaranteed to remain world number one until October 18, 2026, but Zverev can close the gap in Beijing, where he has reached the quarter-finals to face Novak Djokovic.
According to ANSA calculations, if Zverev wins both the Beijing and Shanghai titles, he would mathematically overtake Sinner in the rankings. The German stands at 11,040 points in that scenario against Sinner's 10,950.
Zverev has capitalised on the absences of both Sinner and Carlos Alcaraz to win the US Open after his Roland Garros triumph earlier in the year.
Calendar under strain
The injury has forced Sinner to skip a significant portion of the 2026 season: the Masters 1000 events in Montreal and Cincinnati, the US Open, and now the entire Asian swing including Beijing and Shanghai. The ATP calendar leaves narrow margins for recovery, and Sinner has stated repeatedly that he wants to prioritise his long-term physical health.
September training sessions with coach Simone Vagnozzi and compatriot Flavio Cobolli had raised hopes of an imminent return. Sinner was photographed on court, racket in hand, but his knee has not responded sufficiently well to resume match play.
What comes next
Sinner remains entered in several events before the season ends:
• Six Kings Slam in Riyadh, October 21–24, an exhibition tournament where he is scheduled to face Alex de Minaur
• ATP 500 Vienna, October 26 to November 1
• Paris Masters, November 2–8
• ATP Finals in Turin, November 15–22, where Sinner is defending champion
• Davis Cup Final 8 in Bologna, November 24–29, though his availability for Italy remains unconfirmed
The risk of further withdrawals from Paris and Turin is considered concrete given the lack of a clear timeline for recovery. For Italian tennis fans, the potential loss of Sinner at the ATP Finals in Turin is deeply concerning — this is the most prestigious indoor tournament in Italy and the country’s largest annual tennis event, drawing thousands of local supporters and national media attention. Sinner’s presence has been central to its identity since he claimed the title in 2025.
Equally critical is his uncertain participation in the Davis Cup Final 8 in Bologna, where Italy, as defending champion, is seeking to retain its title. The team, already weakened by injuries, may have to compete without its captain and most consistent performer. Without Sinner, Italy’s chances of progressing beyond the knockout stages are severely diminished — a possibility that would mark a turning point for Italian tennis after their historic rise in recent years.
For Italian tennis fans, the uncertainty is palpable. What began as a precautionary rest after the Wimbledon triumph has evolved into a prolonged absence with no definitive endpoint, at a moment when Sinner's position at the summit of the sport faces its most sustained threat — and Italy’s tennis legacy hangs in the balance.
