Jannik Sinner has undergone surgery to remove his tonsils, a procedure that has contributed to significant weight loss and a drop in muscle tone.
This surgery complicates the Italian star’s recovery from a knee injury that has kept him sidelined since July 12.
The revelation came directly from Sinner via his YouTube series, “Jannik Sinner Unfiltered,” on November 11. While the tennis world had focused primarily on the persistent knee issues that forced his withdrawal from the 2024 Paris Olympics, the tonsillectomy explains the physical setbacks he has faced during his hiatus, as reported by Eurosport.it.
The procedure was deemed necessary following previous health incidents, including a bout of tonsillitis that prevented his participation in those Olympic Games.
According to Corriere della Sera, the athlete has not played tennis since the period around October 6, when he announced his season had ended. His recovery has been complicated by the difficulty of rebuilding muscle mass, as he cannot yet train at full intensity. His ongoing discomfort was inadvertently confirmed by Valentino Rossi, who encountered the tennis star in Milan.
The recent training session with the “Piatti boys” from Bordighera proved particularly difficult, with Sinner stopping after approximately twenty minutes due to pain. “Basta, non ce la faccio,” Sinner said.
“It is the first time I am not in control of what happens and it is strange. It is a feeling I do not like but I have to accept it,” Sinner told Corriere della Sera.

Sinner’s daily routine has shifted from high-intensity court drills to gym work and simulator training. “Norman is similar to Darren [Cahill] and has accepted the way in which we are already working. Nothing will be overturned: Magnus will have to add the 1% to improve even more,” Sinner told Corriere della Sera.
“I have only 25 years, I want to go on for at least another ten. The pressure at this moment is the last of my problems,” Sinner told Corriere della Sera.
“I work every day with the goal of Australia in mind, but let’s wait a little bit: if I rush, more important problems can arise,” Sinner told Corriere della Sera.
