Following his Wimbledon victory on July 12, Jannik Sinner has been sidelined by a right knee injury, previously identified as extra-articular tendinopathy. After withdrawing from several major tournaments, including the US Open and the China Open, Sinner is now evaluating a potential return at the Shanghai Masters 1000.

Sinner is currently nearing a decision regarding his participation in the tournament. To increase his physical readiness, he has been training in Monte Carlo. While he is considered clinically recovered from the tendon inflammation, his staff is closely monitoring his response to on-court intensity to minimize the risk of relapse.

Medical experts note that if pain persists, surgical intervention for potential patellar tendinopathy might be required, which could result in a three-to-four-month hiatus. 

Sinner’s return is under significant pressure regarding his ATP ranking. Alexander Zverev is currently closing the gap, trailing the world number one by 1,370 points. To guarantee maintaining his top ranking, Sinner may need to reach at least the round of 16 in Shanghai.

Amidst the injury concerns, Nick Kyrgios has offered high praise for the Italian, describing him as a ‘machine’ and suggesting Sinner could eventually be remembered as one of the ‘GOATs’ due to his exceptional ability to transition from defense to offense and his improved service game. Kyrgios also stated that Sinner is “one of the best ball strikers that tennis has ever seen.”
