Cape Town - Sharks hooker Chiliboy Ralepelle has reportedly tested positive for a banned substance.
According to Netwerk24, Ralepelle allegedly tested positive in January when a random drug test was executed by the South African Institute for Drug-Free Sport (SAIDS) at Kings Park.
This isn't the first time Ralepelle has been tested positive.
In 2015 he was banned for two years for an anabolic steroid.
It dated back to an out-of-competition doping control test taken the year before when he was recovering from an operation on an anterior cruciate ligament following a knee injury in France.
In 2010, Ralepelle and fellow Springbok Bjorn Basson also tested positive for methylhexanamine, but were found to not be at fault as the substance was apparently contained in Springbok-approved supplements.
The 32-year-old, who has 25 Tests to his name, has not played for the Sharks this Super Rugby season thus far.
Meanwhile, this weekend sees the Sharks take on the Bulls in their SA derby at Loftus Versfeld.
Kick-off on Saturday is at 17:15.
