World number one Jannik Sinner will miss the remainder of the 2026 tennis season after deciding with his doctors to undergo treatment for a knee injury.
The Italian announced the decision in a video message on Tuesday, 6 October. According to Sky Sports, his team said treatment for inflammation in his knee would allow him time to recover before preparing for 2027.
Sinner said protecting his long-term career was central to the decision. A specific date for his return to competition has not been announced.
Wimbledon was his last appearance
Reuters reported that Sinner has not competed since defeating Alexander Zverev in the Wimbledon final on 12 July.
The 25-year-old subsequently missed the North American hardcourt tournaments, the US Open, and the Asian events. He will also miss the European indoor season and the ATP Finals in Turin, where he won the previous two editions.
His Wimbledon victory completed a successful first half of the year. Sky Sports reported that he won six titles in 2026, including five Masters 1000 events, and finished with 44 victories from 47 matches.
The Wimbledon title was his fifth Grand Slam singles trophy.
Vienna confirms his withdrawal
Organisers of the Erste Bank Open confirmed that Sinner would be unable to defend his title at the Vienna tournament, scheduled for 24 October to 1 November.
Tournament director Herwig Straka said Sinner had informed him personally of the decision to end his season. Straka supported his choice to prioritise his career and avoid unnecessary risks.
The tournament’s statement said Sinner would return to the ATP Tour once his knee was no longer causing problems.
Number one ranking remains in contention
Sinner’s absence leaves his position at the top of the rankings under pressure. Sky Sports reported that he held 11,000 points, compared with second-ranked Zverev’s 9,720.
Zverev could move ahead before the season ends, although the final standings have not been decided.
Vienna’s organisers said the German could take the number one position during their tournament. Zverev remains among the leading players scheduled to compete there, alongside Daniil Medvedev, Frances Tiafoe, and Alex de Minaur.
For Sinner, the immediate priority is completing treatment and recovering before beginning preparations for next season.
