Jannik Sinner, the world No. 1 and reigning Wimbledon champion, withdrew from the 2026 US Open on August 21 with a right knee injury that has kept him off the court since July.[^2]

CBS Sports reports that his 2026 major season will end with one Grand Slam title, Wimbledon, which was the only Grand Slam final he reached this year.[^3] The Jamaica Gleaner notes that the injury sidelined him from the moment he claimed the Wimbledon title.

Sinner himself was direct about the cause. Perfil reports that he described a right knee muscle overload that has troubled him since the Masters 1,000 events in Montreal and Cincinnati.[^4] ABC News Australia confirms that the injury has kept him out since his Wimbledon victory in July.[^7]

Media Indonesia reports that his last competitive appearance was that Wimbledon final, where he defeated Alexander Zverev to claim his fifth Grand Slam title.[^5] The same report notes that Sinner had collected six titles in 2026 with a record of 44 wins and three losses, including a sweep of the first five ATP Masters 1000 tournaments of the year.[^6]

The read here is that the withdrawal caps an extraordinary run: a near-perfect season interrupted at its peak by a knee problem that, on the available record, has not resolved over two months. What remains open is whether he will be fit for the autumn hardcourt swing.
