Official: Fonseca Will Not Play the US Open
The Brazilian player has not been able to recover in time from an abdominal injury, so he will not be able to participate in the last Grand Slam of 2026.
The worst predictions have been confirmed: Joao Fonseca will not compete in the US Open 2026. The Brazilian tennis player had already withdrawn from his second-round match at ATP Cincinnati 2026 against Christopher O'Connell, which raised alarms, and a few days later he confirmed that due to an abdominal injury, he will not be able to be in New York for the last Grand Slam of the year.
Fonseca had been playing at a high level for the past few months and was one of the players expected to achieve great things on this tour. However, his body has once again said enough and has deprived him of continuing to climb the rankings, as happened earlier this year due to a back problem. On this occasion, the Brazilian tennis player posted on Instagram explaining what happened and how it pains him not to be at the US Open.
"After undergoing examinations and starting treatment on my abdomen, it became clear to me and my team that I need more time to recover to 100% and to be able to compete at a high level. Therefore, unfortunately, I will not be able to participate in the US Open. It was not an easy decision to make, as it is a very special tournament for me. We continue to work to return as soon as possible. I greatly appreciate the supportive messages and also the birthday wishes, thank you very much," Fonseca wrote.

Fonseca, another significant absence for the US Open
This injury to Fonseca represents another significant absence for New York, which will already be without top players like Jannik Sinner, Jack Draper, or Holger Rune. Additionally, Carlos Alcaraz will also arrive under caution after being 4 and a half months away from the circuit due to a wrist injury. Therefore, the tournament will be more open than ever and opens the possibility for a new player to emerge as champion in New York.
As for Joao, it seems that it is not an injury to be overly concerned about. He has been unlucky as it happened right before a Grand Slam and did not give him time to maneuver, but normally he should be available for the Asian tour in a few weeks. Also, at the end of the year, he defends his title in Basel, so he will have to step up if he does not want to fall dramatically in the rankings.
