Fonseca withdraws from US Open with abdominal injury

Brazilian tennis player Joao Fonseca, ranked 26th, has withdrawn from the US Open 2026 due to an abdominal injury, announcing on social media that he needs more time to recover. The 20-year-old had been a breakout contender after a French Open run to the quarterfinals this year, where he defeated Novak Djokovic and Casper Ruud. Fonseca said the decision was hard but necessary to compete at a high level, sending thanks for support as he focuses on return. The withdrawal adds to a wave of top-name absences at the event, with world No. 1 Jannik Sinner, Jack Draper, and Holger Rune already out with injuries. The field is expected to be more open as several other top players also miss the tournament. Fonseca previously made his US Open main-draw debut last year and has notable quarter-final appearances this season, but will now miss the last Grand Slam of the year.
