World No. 1 Jannik Sinner has announced that he will not be taking part in this year’s US Open after a lingering problem with his right knee forced him to withdraw.

The Italian star, who has been sidelined since his triumph at Wimbledon last month – where he secured his fifth Grand Slam crown by defeating Alexander Zverev in a hard‑fought final – had hoped to recover in time for the New York tournament, but his medical team concluded that additional rest was essential. Sinner’s absence from the professional circuit began shortly after his Wimbledon victory. He missed the Canadian Open in Montreal and then pulled out of the Cincinnati Masters, citing the same knee issue. The decision to skip Cincinnati was made with the intention of preserving his health for the hard‑court swing leading to Flushing Meadows, yet the injury proved more stubborn than anticipated.

In a heartfelt post on social media, the 2024 champion explained the situation: "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 US 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. I'm obviously very sad and disappointed, as New York has a special place in my heart.

I was very much looking forward to coming back and playing in the electric atmosphere in front of the great fans there." The timing of Sinner’s withdrawal is particularly striking because it follows closely on the heels of another headline‑making development: Spain’s Carlos Alcaraz, who defeated Sinner in the 2023 US Open final, announced his own return from a four‑month wrist injury layoff. Alcaraz, now the highest‑ranked player still active on the tour, will be aiming for his third US Open title after previously winning in 2022 and again in 2023. With Sinner out, the draw opens up for other contenders, and Spain’s Carlos Taberner has been moved into the men’s singles field to fill the vacant spot. Former British No.

1 Annabel Croft, speaking to Sky Sports’ Gigi Salmon, described Sinner’s decision as a "big shock" and highlighted the physical toll the modern tour exacts on its top athletes. She noted that both Sinner and Alcaraz have been on relentless schedules, winning multiple Masters 1000 events in quick succession earlier in the year. "When you think at the beginning of the year when he won those five back‑to‑back Masters 1000 titles which was absolutely exceptional and a phenomenal achievement, but when he got to Roland‑Garros there was not much left in the tank and it cost him perhaps the French Open title. Then we saw him rebound at Wimbledon which he built with each match but once again his body has let himself down," Croft explained.

She added that the challenge for players is balancing the need to compete in mandatory tour events while also peaking for the Grand Slams, a balance that has become increasingly precarious. Former world No. 40 Ryan Harrison echoed the sentiment, suggesting that the risk of aggravating the knee injury outweighed any potential reward from playing the US Open. "Sinner feels the risk of playing the US Open is a little bit too much," Harrison said, underscoring the careful calculations athletes must make when their bodies send warning signals.

The rivalry between Sinner and Alcaraz has been one of the most compelling storylines in recent tennis, with both players often meeting in the later stages of major tournaments. Croft lamented that fans will miss the chance to see this new era clash in New York, comparing it to a highly anticipated boxing match.

"It's like watching a big boxing fight. You want to see the very best go up against each other, but now it's an opportunity for the next category down to shine," she said. The absence of the two stars may give rise to fresh faces, but the loss of their head‑to‑head battles is felt across the sport. Looking ahead, the US Open will still feature a strong field, with Alcaraz positioned as the favorite to capture a third title.

The tournament will be broadcast live on Sky Sports from August 30, and viewers can also stream matches via NOW or other authorized platforms. While the event will proceed without Sinner, his withdrawal serves as a reminder of the demanding nature of professional tennis and the fine line athletes walk between ambition and health. In summary, Jannik Sinner’s decision to sit out the US Open stems from a persistent right‑knee injury that has kept him off the court since his Wimbledon victory.

Despite his disappointment and affection for the New York crowd, the priority remains his long‑term well‑being. The tournament will move forward with Alcaraz as the top contender, while the broader tennis community reflects on the physical challenges that elite players face in an increasingly grueling calendar.
