Novak Djokovic has secretly been battling an undisclosed health problem for “many years”.
The 39-year-old tennis star made the admission after falling to his hands and knees and appearing to vomit during a shock defeat at the Cincinnati Open, with the 24-time Grand Slam champion becoming visibly unwell during his second-round match against Argentina’s Thiago Agustín Tirante in Mason, Ohio, on Saturday (15.08.26.)
