B Sample results all but end Springbok's World Cup hopes

After an additional round of testing, Springboks and Sharks hooker Chiliboy Ralepelle’s B-sample also revealed the presence of the banned substance, Zeranol.

The Sharks front row forward failed a random drugs test in January, undertaken by the South African Institute for Drug-Free Sport (SAIDS) at Kings Park.

However, following the A-sample positive result Ralepelle exercised his right to have his B-sample analysed.

SAIDS released a statement on Wednesday, stating that the B-sample also returned a positive for the banned substance, Zeranol .

“The B-sample result of Sharks rugby player, Mahlatse Chiliboy Ralepelle, confirmed the presence of the banned substance, Zeranol. During the sample collection process, the athlete divides his sample into an A-sample container (60ml) and a B-sample container (30ml) and seals both containers. The B-sample container therefore contains the same urine as the A-sample container.”

This is the third time the 32-year-old Sharks hooker failed a drug test. In 2010 he tested positive for methylhexanamine, however, was absolved from any wrongdoing while in 2014 he was banned for two years for an anabolic steroid drostanolone – while playing for Toulouse
