The scoreboard at Flushing Meadows told a story nobody had dared predict. Novak Djokovic, 24-time Grand Slam champion and the most decorated player in the history of tennis, walked off the court in the first round of the 2026 US Open, beaten in five sets by Argentine qualifier Mario Navone. It was not just a shock result — it felt like a turning point. Djokovic's physical distress was visible throughout the match.

Analysts who watched the contest closely, including BBC Sport's Abigail Johnson, noted that an underlying illness has been quietly eroding his movement, his recovery between points, and ultimately his ability to compete at the highest level. This is not a question of motivation or tactics. Something deeper is going wrong, and it has been affecting his results across the entire 2026 season. The debate now shifts from this tournament to the wider arc of his career.

Will Djokovic compete again this year? Those close to the situation are not certain. What does seem increasingly likely, however, is that the Los Angeles 2028 Olympics — should he reach them — could serve as a natural, emotionally fitting farewell to professional sport. Djokovic himself has spoken of his attachment to the Olympic stage, having finally won gold in Paris in 2024 after decades of near-misses.
