Jannik Sinner, new cause for concern: training session cut short. When will he return to the court?

As New York prepares to host the U.S. Open, Jannik Sinner continues his recovery in Europe. The world No. 1 has withdrawn from the U.S. Open due to inflammation in his right knee and, at least for the next few days, will not resume training with a racket. The contrast with the atmosphere at Flushing Meadows is stark. In New York, Fan Week events have already begun, players are putting the finishing touches on their preparations, and the public is gearing up for the Grand Slam, which kicks off on Sunday. Sinner, on the other hand, has chosen a completely different path, aiming to return to the court only when his knee is back in top condition.
After leaving Monte Carlo, Jannik returned to JMedical in Turin, a Juventus facility where he is undergoing his rehabilitation program. He traveled on his own and was welcomed by the center’s staff, where an appointment had already been scheduled to continue his therapy. Sinner underwent new physical therapy sessions as part of the protocol that began in early August. The program was initiated following examinations conducted at the Physioclinic in Milan, a center specializing in the assessment and treatment of injuries. According to reports, the issue with his right knee appears to be due to inflammation without any structural damage. Furthermore, it is not believed to be directly linked to the slips he experienced during Wimbledon, but may have flared up again in late July, when Sinner resumed training following the break after his triumph in London.
In recent days, the ATP No. 1 had nevertheless tried to work on the court, closely monitoring the joint’s response. The goal was to gradually assess the possibility of increasing the workload and regaining normal mobility. However, the feedback received during these tests led Sinner and his staff to err on the side of caution. A complete break from tennis activities has been decided for this week, and it cannot be ruled out that the break may extend into the first few days of September. The target date is therefore September 6, when a new phase of training could begin. At that point, Sinner will assess how his knee is responding and, if things feel positive, he will be able to gradually increase the intensity of his training.
At the moment, there are no indications suggesting a change in plans from what was announced when he withdrew from the US Open. The goal remains a return at the Beijing tournament, scheduled for September 30. Sinner would thus have more than two months from his last match at Wimbledon to complete his recovery and regain the form necessary to compete at the highest level. Following the long forced break, the season will then continue toward the final events on the calendar, with the ATP Finals as the major goal and the possibility of a Davis Cup call-up.
