This year’s Wimbledon champion needs to undergo a “course of treatment” to help with recovery.
Sinner says he’s made the decision to protect his “long-term career”.
Speaking in a video message on social media, the Italian said: “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 last couple of years gave me so many beautiful feelings and emotions, which this year is going to be way different, but I also need to think about my long-term career so I will do everything possible to get back 100 per cent.
“I will thank you already in advance for your support and hope to see you very, very soon on court again. Ciao ciao!”
Sinner beat Alexander Zverev in the Wimbledon final in July to successfully defend his title and claim a fifth major trophy, after also winning the Australian Open in 2024 and 2025 and US Open in 2024.
He picked up six trophies in 2026, preceding his Wimbledon success with victories in the ATP 1000 events at Indian Wells, Miami, Monte Carlo, Madrid and Rome, and won 44 of his 47 matches across the year.
