JOHANNESBURG - Springbok and Sharks hooker Chiliboy Ralepelle is fighting for his rugby career after testing positive for a banned substance.
The doping indiscretion is the third of his career.
Ralepelle tested positive in 2010 on the Springboks end-of-year tour, and again in 2014 when playing for French club Toulouse.
After serving a two-year ban in 2015, Ralepelle now faces a possible lifetime ban from the sport.
Once touted to become the first black Springbok captain, he opens up in an exclusive interview in the video above.
