World number one Jannik Sinner is undergoing medical evaluations in Torino to determine his fitness for the upcoming US Open. After a right knee injury forced him to withdraw from the ATP Masters 1000 tournaments in Montreal and Cincinnati, Sinner has begun training at the Circolo della Stampa Sporting to test his joint's response to movement and direction changes.

Decisive clinical checks are scheduled at J Medical between August 17 and 18. Sinner has indicated he will only travel to New York for the US Open, starting August 30, if he is at 100 percent capacity and playing without pain.
