Overview
- Jannik Sinner collapsed during his Roland Garros match on May 28 and the episode prompted a planned diagnostic workup to probe recurring fatigue seen earlier this season.
- He completed a two‑day day‑hospital check at San Raffaele in Milan on Monday and Tuesday that included blood tests, ECG, echocardiogram, Holter monitoring and a reported cardiac MRI.
- Multiple outlets say the preliminary results showed no alarming structural heart problems, and medical staff cleared Sinner to resume training.
- Sinner left Milan on Tuesday, returned to Monte Carlo and began on‑court preparation on Wednesday while withdrawing from Halle and Queen’s to focus on defending his Wimbledon title.
- The checks were described as precautionary and driven by the heavy spring schedule and repeat episodes of exhaustion; the team will continue to monitor results and adapt his preparation as needed.
