Rugby player, Mahlatse Chiliboy Ralepelle was born in Tzaneen on 11 September 1986. Ralepelle moved to Pretoria and attended Pretoria Boys High School, where he joined the rugby team. He was selected for the under- 15 squad in 2001 and the under-19 squad in 2004.
Ralepelle made history in 2006 when he became the first Black rugby player to captain the Springboks.
In 2010, his reputation was tainted when he was suspended following a drug test that proved positive. It was later discovered though that an energy drink contained a banned substance. Ralepelle was cleared.
In current times, Ralepelle has played for the Sharks and has recently (April 2019) been tested positive by the South African Institute for Drug-Free Sport for the banned drug Zeranol. In public response to these results, he maintains that he did not take any drugs.
