Malaysian badminton star Lee Chong Wei has been banned for eight months for a doping violation, but the backdated suspension means he is free to play from May 1.
The former world number one was suspended by the Badminton World Federation (BWF) doping hearing panel after an adverse analytical finding from a sample taken at last year's BWF World Championship.
Lee's sample contained Dexamethasone, which is prohibited in competition, that came from a food supplement the 32-year-old was taking.
During a hearing on April 11, Lee accepted that Dexamethasone was in his system but argued it was inadvertent.
The three-member panel found Lee had been "negligent", ruling that he be ineligible for eight months.
A BWF statement read: "Lee established how a specified substance [Dexamethasone] entered his body.
"Lee established the specified substance [Dexamethasone] was not intended to enhance the sport performance or mask the use of a performance-enhancing substance.
"And Lee produced corroborating evidence which "to the comfortable satisfaction of the panel" supported the absence of any intent on his part."
Lee's ban was backdated to August 30 last year – and his runner-up result in the men's singles at the World Championship has been disqualified.
Results obtained between August 30 and the day Lee was notified of his positive test - October 2 last year - will stand.
Lee was provisionally suspended in November last year, pending his hearing.
He has already signalled his intention to play in the team event at the Southeast Asian (SEA) Games, which start on June 5.
