Badminton: Zhou Mi seeks to quash drugs ban

Former World No 1 badminton player Zhou Mi has submitted expert evidence in support of her attempt to overturn a two-year doping ban.

Zhou claims she unknowingly ingested clenbuterol by eating pork tainted with the banned drug. Clenbuterol has been used in cattle and pig raising in China.

The World Badminton Federation banned Zhou in 2010 after a urine sample came back positive for clenbuterol.
