Jannik Sinner will not return to the court this season after deciding to prioritise treatment for the knee injury that has kept him sidelined since winning Wimbledon.
The world number one announced on Instagram that he would be stepping away from tennis for the remainder of the year in order to focus on his ‘long-term career’.
‘Hello everyone, I would like to give you a little update,’ he said in the video.
‘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.’
The decision means Sinner will miss both the Davis Cup Finals in Bologna and next month’s ATP Finals in Turin – a tournament he admitted he was particularly disappointed to miss.
‘The last couple of years, especially the ending in Turin, gave me so many beautiful feelings and emotions, which this year is going to be way different,’ he added.

‘But at the moment, I also need to think about my long-term career. I will do everything possible to get back 100%.’
Why Jannik Sinner Is Ending His Season Early
Sinner’s team said the issue is inflammation in his right knee, and it’s understood he will not require surgery.
It’s been another remarkable season for the Italian, who has dominated the men’s game for much of the year.
He won 44 singles matches while losing just three, claimed five consecutive Masters 1000 titles between March and May and became the youngest man to complete the career Golden Masters.
Overall, Sinner lifted six titles in 2026 across hard, clay and grass courts, defeating world number two Alexander Zverev in two of those finals.
What This Means for the ATP Rankings
His early end to the season also opens the door for Zverev to finish the year as world number one. The German currently sits just 1,280 ranking points behind Sinner in the live ATP rankings, with several tournaments still to play.
