World No. 1 Jannik Sinner has officially ended his 2026 season to prioritise recovery from a right knee injury (inflammation, specifically extra-articular tendinopathy linked to iliotibial band syndrome/ITBS), which has kept him off the court since his Wimbledon triumph in July.
On October 6, 2026, the 25-year-old Italian announced the decision in a video message shared on social media (X/Instagram).
“Me, together with the doctors, have decided that I need a course of treatment for my knee which means the 2026 season is officially over,” Sinner said. He reflected that recent years—especially the endings in Turin—brought “so many beautiful feelings and emotions,” but this year would be different. “But at the moment, I also need to think about my long-term career. So I’ll do everything possible to get back 100%.” He thanked fans in advance and expressed hope of returning “very, very soon on court again.”
His management team confirmed he will follow a course of treatment for inflammation in the knee. The decision prioritises full recovery time before preparations for 2027 begin, ruling him out of remaining events including the European indoor hardcourt swing, the Paris Masters, the Nitto ATP Finals in Turin (where he was two-time defending champion), and Davis Cup Final 8 duties for host and three-time defending champion Italy.
Timeline of the Injury and Absences
Sinner’s last competitive match was the Wimbledon final on July 12, 2026, where he defeated Alexander Zverev to successfully defend his title and claim his fifth career Grand Slam (and second consecutive at SW19).
Reports indicate the issue may have roots in an awkward fall/rotation during his five-set first-round win at Wimbledon (against Miomir Kecmanovic), though symptoms became more evident during post-Wimbledon training for the North American hardcourt swing.
He subsequently withdrew from the Canadian Open (Montreal), Cincinnati Open, US Open (right knee injury cited), China Open in Beijing (where he was defending champion), and Shanghai Masters.
Attempts at rehabilitation—including work at J Medical in Turin involving physiotherapy, shockwave therapy, gym strengthening, sand exercises, swimming, and progressive loading—plus consultations (notably with orthopaedic specialist Bertrand Sonnery-Cottet in Lyon) led to the conservative treatment path.
Treatment is expected to involve several weeks of reduced loading followed by gradual reconditioning.
2026 Season Achievements Despite the Abrupt End
Despite the early finish, Sinner delivered an outstanding campaign: a 44–3 singles record (approximately 93–94% win rate), six titles, and dominance across surfaces. Key highlights include:
• Australian Open semifinals (loss in five sets to Novak Djokovic).
• A historic run of five consecutive ATP Masters 1000 titles (Indian Wells, Miami, Monte-Carlo, Madrid, Rome), making him the youngest man to complete the Career Golden Masters and the first to win five in a row. This included a stretch of three consecutive titles without dropping a set and a career-best 30-match winning streak that ended with a shock second-round loss to Juan Manuel Cerúndolo at the French Open amid extreme heat/humidity.
• Wimbledon title defence, overcoming a gruelling first round (bleeding through shoes at one point) en route to beating Zverev in the final.
• Strong head-to-head form (e.g., 10–1 against top-10 opponents, sole loss to Djokovic in Melbourne; victories over Zverev and Carlos Alcaraz in key finals).
He earned substantial prize money (around $11.5–11.6 million for the season) and extended his time as world No. 1. Career totals at the time of the announcement stood near 30 titles and a strong overall win percentage.
Looking Ahead to 2027
The priority is a complete recovery to protect long-term career longevity. A return in time for the Australian Open (mid-January 2027) is a realistic target if rehabilitation progresses well, though full intensity will depend on medical clearance and progressive loading. Sinner has emphasised rationality and long-term thinking over short-term returns that risk setbacks.
