South Africa have begun investigating an alleged racist slur directed at England flanker Tom Curry by their hooker Mbongeni Mbonambi.
England have until Monday morning (Monday evening AEDT) to lodge a complaint with the citing officer after Curry claimed he had been the victim of a discriminatory remark in Saturday's 16-15 World Cup semi-final defeat by the Springboks.

Curry drew the incident to the attention of referee Ben O'Keeffe in the second quarter of the match at the Stade de France.
Although the alleged slur is not audible on the ref mic, Curry's subsequent conversation with O'Keeffe is.
"Sir, if their hooker calls me a white c*** , what do I do?" the Sale flanker said.
O'Keeffe replied: "Nothing, please. I'll be on it."
South Africa responded on Sunday by confirming they are looking into the incident.
"We are aware of the allegation, which we take very seriously, and are reviewing the available evidence. We will engage with Bongi if anything is found to substantiate the claim," an SA Rugby statement read.
When asked after the match if Mbonambi had said something he should not have done, Curry replied "yeah", although he declined to reveal the content of the remark.
Mbonambi, who took over as captain once Siya Kolisi had been replaced, refused to shake Curry's hand at the end of a dramatic clash in Paris that was won by Handre Pollard's penalty after 78 minutes.
England led for all but five minutes of the semi-final and were nine points ahead until RG Snyman went over in the 70th minute at a time when the Springboks' scrum was taking control through the introduction of the 'Bomb Squad'.
Jonny May said England's heroic effort against the world champions was fuelled by the belief that they had been dismissed as a serious threat by South Africa.
"I'll be honest, I don't think necessarily the South Africans respect us," May said.
"Some of the things their coach has openly said about us in their documentaries and stuff probably just adds fuel to the fire.
"We touched on their documentary and we've got staff who were with them and they gave us insight of how they feel about us."
England head coach Steve Borthwick declined to speak about Curry's allegation.
"The situation around that is that I'm not going to comment on anything regarding that incident," Borthwick said.
