Sinner US Open 2026 Withdrawal: Knee Injury Reshapes the Draw

The Sinner US Open 2026 withdrawal landed on Friday, August 21, and it is a right knee injury that does it: the world No. 1 will miss a Grand Slam for the first time since he made his major debut at this tournament in 2019. The US Open published the withdrawal on its own site on August 21, with the ATP Tour and ESPN carrying the same statement. The men's singles draw is made on Thursday, August 27, which means the field that gets bracketed will not include the defending finalist and 2024 champion.

Sinner US Open 2026 withdrawal: what was announced

Sinner's statement, reproduced identically by the ATP Tour and ESPN, reads: "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." He added that he still needs more time to recover from his right knee issue.

The knee is not new. Sinner has not played since the Wimbledon final, where he was defending his title against Alexander Zverev, and the same problem already cost him the National Bank Open and the Cincinnati Open earlier in the summer. StatSniper covered the Cincinnati withdrawal when the New York question was still open. It is now closed.

The Sinner US Open 2026 withdrawal is therefore a pre-draw event, which is the part that matters for anyone pricing it. Three dates frame everything that follows. Seedings come off the rankings published Monday, August 24. The singles draw is made Thursday, August 27. Main-draw play begins Sunday, August 30.

The draw math, and what is not yet knowable

Six men have withdrawn from the men's singles: Sinner, Korda, Nava, Davidovich Fokina, Quinn and Diallo. Of those six, Sinner and Davidovich Fokina are the two who would have been seeded.

That distinction matters more than the raw count. Four of the six were outside the seeding cut. The other two were inside it, and one of those two is the world No. 1.

Here is what is genuinely not known yet, and where most of the coverage this week will get ahead of itself. The seeding order after Sinner's exit is not official until the draw on August 27. A projection slotting Zverev into the No. 1 seed and Carlos Alcaraz into No. 2 has circulated, but it comes from a single outlet rather than from the tournament. This post is not going to print a bracket that does not exist.

The reasoning from here is ours rather than the tournament's. When the highest-ranked player comes out before a draw is made, the seeding order below him shifts up a rung, and every seed from two down inherits a slightly softer quarter. That is why one withdrawal at the top of a field is worth more to a bettor than several from outside the seeding cut.

Betting and DFS impact

The discipline note first. No dated, timestamped US Open outright price from DraftKings or FanDuel was obtainable at the time of writing, so this post prints none. Structure only.

Expect every remaining outright to shorten, and not by equal amounts. Removing the world No. 1 does not distribute his implied probability evenly across the field. It concentrates in the players who were priced to lose to him, which in a hard-court major means the top handful and nobody else. A player whose likely path ran through Sinner has more to gain from his absence than one who was never going to meet him. That is direction, not a price we observed.

Wait for the draw before touching quarter or half markets. Reaching-the-final and quarter-winner markets cannot be priced honestly until Thursday. Anything quoted on those before August 27 is pricing a bracket the tournament has not made.

Alcaraz is the name the market will move first, and he carries his own question. StatSniper covered his own return from a wrist injury earlier this week. A field that loses its top seed does not automatically make a player returning from injury a safe favourite. Those are two separate pieces of information and they should be priced separately.

For DFS and matchup markets, the first week gets softer, not sharper. More qualifiers and lucky losers in the main draw means more matches where the form data is thin, which widens the gap between a modelled line and a posted one.

What to watch next

Monday, August 24 is the ranking snapshot that sets the seeds. Thursday, August 27 is the draw itself, and the first moment any bracket-dependent market can be priced on facts. Sunday, August 30 is first ball.

The other thing worth watching is what Sinner's camp says next about a timeline. The statement addressed this tournament and nothing beyond it. Nothing in the current reporting establishes a return date, so treat any date that appears without a named first-tier source accordingly.
