Springbok hooker Bongi Mbonambi has been accused of using a racial slur towards England flanker Tom Curry during their Rugby World Cup semi-final in Paris.
The South African rugby union says they are aware of the allegation and have started their own investigation.
The Springboks play New Zealand in next Saturday's Rugby World Cup final with both sides chasing a record fourth title.
Jan de Koning, editor of the sports news site Rugby365, was at a Springbok media stand-up earlier this morning.
De Koning spoke to Corin Dann.
