At the height of his powers, Jannik Sinner finds himself reminded that the body, unlike ambition, cannot be willed into readiness. The world's top-ranked tennis player has withdrawn from the 2026 US Open — the very tournament he won in 2024 — as a right knee injury refuses to yield to either medicine or determination. In his absence, the tournament's story must be written by others, and the sport is left to reckon with how fragile dominance can be, even at its most convincing.
World No. 1 Sinner withdraws from US Open with right knee injury
New York has a special place in my heart
Mark
Why does missing one tournament matter so much when Sinner has had such a dominant year?
Mimi
Because Grand Slams are the only tournaments that truly define a player's legacy. Forty-four wins in smaller events doesn't compare to one major championship. Missing the U.S. Open, especially when you're defending champion, is a significant gap in your resume for the year.
Mark
But he's already won five Grand Slams at 25. Isn't one missed tournament just a footnote?
Mimi
Not really. The U.S. Open is the last major of the year—it's where you can cement a season as historic or merely good. And for Sinner specifically, New York has become his home court. He won there in 2024, reached the final in 2025. Missing it feels like an interruption of something he was building.
Mark
The injury happened after Wimbledon, right? Why didn't he rest then instead of trying Montreal and Cincinnati?
Mimi
That's the calculation every player makes. You think rest and light practice will be enough. You don't want to miss tournaments if you can help it. But when you test it in real competition and it's not ready, you have to stop. By the time he tested it in Monte Carlo, it was clear he needed more than a few days.
Mark
What does this mean for his year overall?
Mimi
It's still been extraordinary—44-3 with five majors is historic. But there's a shadow now. If someone else wins the U.S. Open, the narrative becomes about Sinner's injury derailing what could have been a perfect season. That's how sports memory works.
Mark
And Alcaraz coming back changes everything?
Mimi
Completely. Alcaraz has won the U.S. Open twice. Without Sinner, he's suddenly the favorite again. The tournament goes from being about whether Sinner can repeat to being about whether Alcaraz can reclaim his throne. It's a different story entirely.
Der Puls
- A 44-3 season and five Grand Slam titles could not protect Sinner from a knee injury stubborn enough to outlast weeks of treatment and two warm-up tournament withdrawals.
- The defending US Open champion's absence tears a significant hole in the draw, removing the clear favorite and forcing the rest of the field to reimagine what winning in New York now means.
- Sinner's own words carried the weight of reluctance — a player who loves the electric atmosphere of New York compelled to choose recovery over the sport's grandest stage.
- Into the vacuum steps Carlos Alcaraz, returning from his own injury absence since April, recasting the tournament's narrative around a rivalry that will have to wait yet again for its next chapter.
At the height of his powers, Jannik Sinner finds himself reminded that the body, unlike ambition, cannot be willed into readiness. The world's top-ranked tennis player has withdrawn from the 2026 US Open — the very tournament he won in 2024 — as a right knee injury refuses to yield to either medicine or determination. In his absence, the tournament's story must be written by others, and the sport is left to reckon with how fragile dominance can be, even at its most convincing.
Jannik Sinner will not be in New York to defend his US Open title. The 25-year-old Italian, ranked first in the world, announced his withdrawal from the year's final Grand Slam on Friday, citing a right knee injury that has resisted recovery despite sustained work with his medical team. It is the first major he has missed since his Grand Slam debut at the same tournament in 2019.
The withdrawal arrives at a jarring moment. Sinner has been the sport's dominant force in 2026 — a 44-3 record, six titles, and a Wimbledon victory over Alexander Zverev that gave him his fifth Grand Slam and seemed to set him up perfectly for another deep run in New York. But the knee, which surfaced as a concern before the North American hard-court season, proved more persistent than expected. After Wimbledon, he returned to Monte Carlo to test his fitness and found the answer was not yet. He had already skipped Montreal and Cincinnati; skipping the US Open itself signals how seriously the injury is being taken.
In announcing his decision on social media, Sinner was candid about the difficulty of the choice. He spoke warmly of the US Open's atmosphere and its fans, and the tone carried genuine reluctance — not a player stepping back casually, but one forced to weigh long-term health against the pull of competition at the sport's highest level.
The season has had its turbulence beyond the injury. A stunning second-round collapse at the French Open — surrendering a two-set lead to Juan Manuel Cerundolo in the heat — preceded a full withdrawal from competition until Wimbledon, where his return was emphatic. That victory seemed to restore his trajectory. Now, the knee has interrupted it again.
With Sinner out, the draw opens considerably. Carlos Alcaraz, sidelined since April with a wrist injury, announced his return to competition just a day before Sinner's withdrawal. The two-time US Open champion will now enter as one of the tournament's leading favorites, offering a different but compelling story for the fortnight ahead.
Jannik Sinner, the world's top-ranked tennis player, will not defend his U.S. Open title this year. On Friday, the 25-year-old Italian announced his withdrawal from the year's final Grand Slam tournament, citing a right knee injury that has not healed sufficiently despite weeks of work with his medical team. It is the first Grand Slam he has missed since making his major debut at the U.S. Open in 2019.
Sinner's absence marks a significant disruption to what has otherwise been a dominant season. Through the middle of August, he had compiled a 44-3 record with six titles, establishing himself as the clear favorite at most tournaments he entered. His victory at Wimbledon last month—a triumph over Alexander Zverev—gave him his fifth Grand Slam title and seemed to position him perfectly for a strong run in New York, where he won the championship in 2024 and reached the final the following year.
But the knee injury, which first surfaced before the hard-court swing in North America, has proven more stubborn than anticipated. After his Wimbledon win, Sinner returned to Monte Carlo to test his fitness over a few days of practice. The assessment was clear: more time was needed. He had already withdrawn from tournaments in Montreal and Cincinnati, both crucial hard-court warm-ups that typically precede the U.S. Open. The decision to skip New York itself underscores the seriousness of the injury.
In his announcement on social media, Sinner expressed genuine disappointment. He acknowledged the difficulty of the choice and spoke of his affection for the U.S. Open and its fans, describing the atmosphere in New York as electric and special to him. The tone was one of reluctance rather than indifference—a player forced to prioritize recovery over competition, even at the sport's highest level.
The season has not been without complications. At the French Open in June, Sinner suffered a stunning collapse in his second-round match against Juan Manuel Cerundolo, squandering a two-set lead while struggling in the heat. He then withdrew from competition entirely until Wimbledon, where his return to form was emphatic. That victory seemed to reset his year and position him as the tournament favorite heading into the U.S. Open's hard courts.
Sinner's withdrawal reshapes the competitive landscape in New York. Carlos Alcaraz, who has been sidelined since April with a right wrist injury, announced his return to competition on Thursday. The two-time U.S. Open champion and three-time Grand Slam winner will now be among the favorites in Sinner's absence, offering fans a different narrative for the tournament's final week. Without the world No. 1 in the draw, the path to the title opens considerably for the remaining contenders.
