World No. 1 Jannik Sinner has withdrawn from the 2026 US Open after failing to fully recover from a right knee injury. The Italian tennis star confirmed the decision on August 21, ending hopes of defending his place among the tournament’s leading contenders at Flushing Meadows.
Sinner’s withdrawal is a major blow to the US Open field. The five-time Grand Slam champion was scheduled to return to New York after winning Wimbledon in July, but his ongoing knee problem has forced him to extend his recovery.
Why Is Jannik Sinner Missing the US Open?
Sinner will miss the US Open because of a right knee injury that has kept him out of competition since his Wimbledon triumph.
According to his team, Sinner has been working with his medical and performance staff but determined that he needs additional recovery time. He recently returned to on-court training in Monte Carlo, where he and his team assessed his condition before making the decision to withdraw.
The US Open main draw is scheduled to begin on August 30, but Sinner will not be part of the tournament this year.
Sinner expressed his disappointment at missing one of his favorite tournaments, saying New York holds a special place in his heart. He had been looking forward to competing in front of the tournament’s fans but acknowledged that his knee requires more time to recover.
Jannik Sinner’s Remarkable 2026 Season
Despite the injury setback, Sinner has enjoyed an outstanding 2026 campaign.
The Italian began the year with an extraordinary run across the ATP Masters 1000 events. He won the first five Masters 1000 tournaments of the season at Indian Wells, Miami, Monte Carlo, Madrid and Rome.
Sinner enters his US Open absence with a 44-3 win-loss record and six titles in 2026. His season also includes another major championship at Wimbledon, where he defeated Alexander Zverev in the final.
The Wimbledon victory was Sinner’s fifth Grand Slam title and his second consecutive championship at the All England Club.
Sinner’s Wimbledon Success
Sinner’s most recent competitive appearance came at Wimbledon, where he successfully defended his title.
His path to the championship included a five-set battle against Miomir Kecmanovic in the opening round. After that difficult start, Sinner did not drop another set on his way to the final.
In the championship match, Sinner defeated Roland Garros champion Alexander Zverev in four sets to secure another major title.
The victory appeared to place him in a strong position heading into the North American hard-court swing. However, the knee problem prevented him from competing in the lead-up tournaments in Montreal and Cincinnati.
First Grand Slam Absence Since 2019
Sinner’s withdrawal has another important significance.
The 25-year-old will miss a Grand Slam tournament for the first time since making his major debut at the 2019 US Open.
His absence also changes the dynamics of the men’s draw. Sinner had been one of the biggest favorites for the championship after winning the tournament in 2024 and reaching the final again in 2025.
He defeated Taylor Fritz in straight sets to win the 2024 US Open title before losing to Carlos Alcaraz in the 2025 final.
Sinner and Carlos Alcaraz Rivalry Takes Another Turn
The rivalry between Sinner and Carlos Alcaraz has become one of the defining stories in modern men’s tennis.
The pair have repeatedly met in major matches, with their battles helping shape the current era of the sport. Sinner’s absence means Alcaraz will enter the 2026 US Open without his biggest recent rival in the draw.
Alcaraz has also dealt with his own injury problems this season. The Spaniard recently confirmed that he would return for the US Open after spending several months away from competition because of a wrist injury.
With Sinner out, Alcaraz becomes an even bigger focus heading into the tournament.
When Could Jannik Sinner Return?
Sinner’s team is targeting a return during the Asian swing of the ATP calendar.
The current plan is for the Italian to potentially compete at tournaments in Beijing and Shanghai, although his exact return date will depend on his recovery.
For now, Sinner will remain in Europe and continue rehabilitation alongside his medical and performance team.
His priority is to regain full fitness rather than rush back for the final Grand Slam of the season.
What Sinner’s US Open Withdrawal Means
Sinner’s absence leaves a significant gap in the US Open field. As the world No. 1 and a former champion, he was expected to be one of the central figures in the tournament.
His withdrawal also provides an opportunity for other contenders to challenge for the title. Alcaraz, along with the rest of the leading players, will now face a tournament without Sinner in the draw.
For Sinner, however, the immediate priority is recovery. After winning six titles and compiling a 44-3 record during an exceptional 2026 season, the Italian will now focus on getting his right knee healthy before returning to competitive tennis.
