Tennis: World number one Sinner will not play in 2026 due to knee injury

What the report says

Jannik Sinner, the world number one in men’s tennis, will not play again in 2026 because of a knee injury that has sidelined him since Wimbledon in July, according to Al Jazeera’s report based on statements from his team and posted on his social media account. The 25-year-old Italian has not competed since winning the title at the All England Club and has continued to miss events while managing inflammation in his knee.

Sinner’s team said he will undergo treatment now so he can recover fully before preparing for the 2027 season. The announcement means he will miss the rest of the year’s major events, including the Paris Masters, the ATP Finals in November and Italy’s Davis Cup Final 8 campaign. He had already pulled out of the Shanghai Masters and missed the North American hardcourt swing, including the US Open.

The report notes that Sinner’s absence could affect the top ranking, depending on results from other players. It also places his injury in the context of a season in which he had built a long winning streak before earlier setbacks. More broadly, the situation matters because Sinner has been one of the sport’s leading figures and his continued absence reshapes the end of the men’s tennis calendar.
