British number one Jack Draper has withdrawn from the Japan Open after trailing Ugo Humbert, having lost the first set 7-5 and struggling with abdominal pain in the second. Despite taking a medical timeout, he was unable to continue. Draper recently reached his first Grand Slam semi-final at the US Open, where he faced health issues during his match against Jannik Sinner. This latest retirement raises concerns about his ongoing sickness problems, which he previously attributed to both physical and psychological stress. Humbert will advance to face Tomas Machac for a spot in the final.
