KUALA LUMPUR (AFP) - The Badminton World Federation (BWF) has set April 11 for the long-awaited doping hearing involving Malaysian ace Lee Chong Wei, a top official said on Tuesday.

The former world No. 1 is temporarily barred from competition after failing a drugs test at last year's World Championships and could face a two-year ban.

Lee tested positive for the banned anti-inflammatory drug dexamethasone at the worlds last August in Copenhagen where he lost to China's Chen Long in the final.

Lee, 32, who said he received dexamethasone during stem cell treatment for a thigh injury last July, has maintained that he will retire if he is banned for two years.

Badminton Association of Malaysia general manager Kenny Goh said the hearing will be held in Amsterdam where Lee's lawyer will submit documents to a three-man panel.

Despite topping the rankings for years and reaching five world and Olympic finals, he has never been able to win either of badminton's two major titles.
