Jannik Sinner accelerates comeback with first training session since US Open withdrawal
ATPTuesday, 08 September 2026 at 06:30
Jannik Sinner has taken another important step towards his return to competition, getting back on a tennis court in Turin just one day after offering a positive update on his injured right knee at the Italian Grand Prix in Monza. The world No. 1 is now targeting the Asian swing as he continues his recovery.
Sinner spent Sunday away from tennis, first travelling to Monza to watch his friend Kimi Antonelli claim victory at the Italian Grand Prix before heading to the Allianz Stadium to watch AC Milan draw with Juventus. When asked about his knee in the paddock, the Italian gave a brief but encouraging update: “Everything is fine.”
The following day, however, Sinner was back on court. According to Torino Cronaca, the four-time Grand Slam champion was seen training at the Circolo Stampa Sporting in Turin, working alongside members of his team as he began testing the knee with a racket in his hand. He was also seen signing autographs for fans who gathered around the courts.
It marks the latest stage of a recovery that has kept Sinner out since his Wimbledon triumph. The Italian withdrew from Cincinnati before eventually pulling out of the US Open, explaining that his right knee still needed more time to recover. The goal now is clear: return without taking unnecessary risks.
Sinner puts his knee to the test
The session in Turin is particularly significant because Sinner is not simply continuing his physical rehabilitation. He is beginning to test how the knee responds to tennis-specific movements, with further work planned alongside his medical and physical teams. Italian reports indicate that he will continue treatment and testing in Turin before another assessment later in the week.
The timeline remains dependent on how the knee reacts, but Sinner's sights are firmly set on China. The current plan is to return at the ATP 500 in Beijing, where he would defend the title he won last year, before potentially continuing to the Shanghai Masters. Beijing is scheduled for September 30 to October 6, followed by Shanghai from October 7 to 18.
That would give Sinner several weeks to build back towards competition after missing the US Open. More importantly, his first session in Turin provides an early indication that the comeback is moving forward. For now, the priority remains the same: make sure the knee is ready before the world No. 1 returns to a tournament.

China could mark Sinner's return
Beijing would give Sinner the chance to return to competition at a tournament where he is the defending champion. Last year, the Italian won the China Open for the second time, defeating American teenager Learner Tien 6-2, 6-2 in the final. That means his return would come with points to defend, before the attention shifts to the Shanghai Masters and the final stretch of the season.
There is still no guarantee that Sinner will be ready for Beijing, with his return ultimately depending on how the knee responds to the increasing workload. For now, though, getting back on court in Turin is another positive sign. After weeks away from competition, the world No. 1 is finally moving from rehabilitation towards the part of the comeback that matters most: preparing to play matches again.
