Eastern Cape boxers Siviwe Hasheni and Ntobeko Duma are now facing a ban of between six and 12 months should they be found guilty of using a prohibited substance.

This follows the SA Institute for Drug-Free Sport's (Saids) detection of f 11-nor-delta9-tetrahydrocannabinol-9-carbolyx acid, which is a metabolite of cannabinoids (a product of dagga) in their urine samples taken on March 31.

The samples were taken after Mdantsane-based Hasheni topped Duma from Butterworth in the third round during an Eastern Cape junior featherweight title at the Mdantsane Indoor Sports Centre.

Boxing SA has already been informed by Saids that the boxers will appear before a disciplinary committee set for Cape Town on July 10. A Boxing SA official will represent the boxers at the hearing.

Saids doping control manager Fahmy Galant said on Tuesday: "There is nothing much I can say about this case other than we have scheduled a hearing in July."

Loyiso Mtya, director of operations at Boxing SA, said: "We've got correspondence from Saids and there is going to be a disciplinary hearing in Cape Town next month."

Hasheni and Duma's handlers have been informed about the matter.

Mamali Productions boss Siphatho Handi, who promotes Hasheni, said: "I have been informed about the findings of the doping test. But I have not yet seen the charge sheet."

Duma's manager Lunga Mbanga confirmed that "my boxer is going to appear before a Saids hearing next month after traces of cannabis were found in his urine sample".

Last year Julie Queen Shabalala, a mother of three from Johannesburg, became the first female boxer in South Africa to fail a drug test. This comes after traces of the same metabolite were found in her sample after an eight-round victory over Lillian Molala in August. The concentration was 75ng/ml. WADA's limit is 18ng/ml. Shabalala was suspended for three months and her ban ended on December 26.
