Sinner won Wimbledon in July before his knee problem.
He has missed the North American hard‑court events and the Asian tournaments.
The decision was made with doctors to protect his long‑term career.
He will also miss the European indoor hard‑court series and the final tournament of the year.
His absence could let another player move to the top ranking.
He chose to stop playing for the rest of 2026 so his knee can heal.
Doctors will give him special care to reduce the swelling.
Missing the season means he won’t play in big events like the United States Open or the season‑ending finals.
He plans to be ready to compete again in 2027.
