ROME, Oct 6 — Tennis world number one Jannik Sinner has brought a premature end to his season due to a knee injury, the Italian announced today.

“Me, together with the doctors, have decided that I need a course of treatment for my knee, which means that the 2026 season is officially over,” Sinner said in a video posted on social media.

The 25-year-old’s announcement came just over a month before he was due to defend his crown at the ATP Finals in Turin.

Sinner had finished the previous two seasons on a high by winning in Turin, leading to “so many beautiful feelings and emotions”, he said.

“This year is going to be way different,” he acknowledged. “But at the moment, I also need to think about my long-term career.”
