Jannik Sinner withdraws from US Open due to knee injury

World number one Jannik Sinner has withdrawn from the 2026 U.S. Open due to a persistent right knee injury, marking a significant shift in the men’s tennis landscape ahead of the season’s final Grand Slam. The 24-year-old Italian, who captured his fifth career Grand Slam title at Wimbledon in July, announced the decision on Friday, citing ongoing recovery challenges following the injury sustained earlier this month.

Sinner’s absence deprives the tournament of one of its most dominant players, with the 24-year-old having led the ATP rankings since late 2025. His withdrawal comes a day after rival Carlos Alcaraz confirmed his participation at Flushing Meadows, despite a four-month hiatus due to a wrist injury. Alcaraz, the defending U.S. Open champion, now faces a path to the title without his primary competitor, though the Spaniard’s return has been met with cautious optimism given his recent medical history.

The Italian’s decision follows a series of absences from key lead-up events. Sinner skipped the Montreal and Cincinnati Masters 1000 tournaments, both critical hard-court preparations for the U.S. Open, and has not played competitively since his Wimbledon victory. In a statement released via social media, Sinner emphasized the difficulty of the choice, stating, “Even though I have been working hard with my team and my medical staff, we have now had to make the difficult decision that I will not be able to compete at the U.S. Open this year.”

“We have been back on court in Monte Carlo over the last couple of days and have realised that I still need more time to recover from my right knee issue,” he added. The statement echoed similar remarks in reports from other outlets, though the exact timeline of the injury remains unspecified. Sinner’s team has not provided further details on the nature of the knee problem, but the withdrawal underscores the physical toll of the sport’s demanding schedule.

The impact of Sinner’s absence extends beyond the court. The Italian had been a key figure in the men’s tour, amassing a 44-3 record this season and securing six titles, including five Masters 1000 events. His absence creates a vacuum in the upper echelons of the rankings, with Alcaraz and other top players now vying for dominance. The U.S. Open, traditionally a proving ground for elite talent, will now lack one of its most consistent performers, though the tournament’s depth remains intact.

Alcaraz’s return to Flushing Meadows has drawn particular attention, as the Spaniard seeks to reclaim his title and expand his Grand Slam tally. His participation, however, is not without risks. The wrist injury that sidelined him for four months has raised questions about his readiness, though he has expressed confidence in his recovery. Sinner’s withdrawal removes a direct obstacle, but the tournament’s outcome will still depend on a mix of form, strategy, and resilience.

Sinner’s emotional response to the decision highlighted the personal stakes involved. “I’m obviously very sad and disappointed, as New York has a special place in my heart,” he said. The U.S. Open, known for its electric atmosphere and passionate fanbase, has long been a highlight of the tennis calendar for the Italian. His absence leaves a void not only in the competition but also in the narrative of the tournament.

The withdrawal also raises broader questions about the sustainability of the sport’s intense schedule. Sinner’s injury and Alcaraz’s recent struggles with wrist issues reflect the physical demands faced by top players. As the tennis calendar continues to expand, the balance between competition and player welfare remains a topic of discussion among athletes and officials alike.

With Sinner out of the picture, the U.S. Open will see a reshaped competitive landscape. While Alcaraz’s return offers a compelling storyline, the tournament’s outcome will hinge on the performance of a diverse field of contenders. For now, the focus shifts to the players who will take the court, as the final Grand Slam of 2026 prepares to unfold without one of its most formidable stars.
