World number one Jannik Sinner will not play for the rest of 2026 because of a knee injury, for which he will undergo treatment. "At the moment, I...need to think about my long-term career...I will do everything possible to get back 100%," he said. Sinner has not played since winning his fifth Grand Slam title at Wimbledon in July.
