China's Yu Xiaohan was on Monday provisionally suspended by the Badminton World Federation (BWF) due to an apparent anti-doping regulation violation.
"The provisional suspension under Article 7.9.2 of the BWF Anti-Doping Regulations means the athlete is barred temporarily from participation in any competition prior to the BWF Doping Hearing Panel's decision," a BWF statement said.
The BWF imposed the suspension on September 28 due to an "adverse analytical finding of a sample taken at the 28th Summer Universiade in Gwangju in July". The case was passed to the BWF by the International University Sports Federation (FISU), which declared a doping rule violation by Yu.
The BWF has referred the matter to its Doping Hearing Panel and a date in late January 2016 has been set for the hearing.
