World Rugby said on Monday that it will investigate an allegation of racism leveled against South African hooker Bongi Mbonambi by England flanker Tom Curry during their World Cup semi-final in Paris.

Curry claims Mbonambi used a racial slur against him during the first half of the Springboks' 16-15 victory, which set up a final match with old rivals New Zealand at the same site on Saturday.

"World Rugby takes all allegations of discriminatory behaviour extremely seriously," the organization stated in a statement.

"We can confirm that we are formally reviewing the allegation made by England's Tom Curry regarding the use of discriminatory language during Saturday's Rugby World Cup 2023 semi-final between England and South Africa."

"World Rugby will not be making further comment until the conclusion of the process."

South African Rugby announced on Sunday that it had initiated its internal investigation and was "reviewing the available evidence."

Curry complains to referee Ben O'Keeffe in audio and video evidence released on social media, but no action is taken, and the alleged slur is not heard.

When questioned by reporters later, Curry confirmed an incident but refused to say what was allegedly said.

On Sunday, England coach Steve Borthwick refused to comment on the accusation.

If Mbonambi is found guilty, he will almost certainly face a suspension, which would be a significant blow to the Boks ahead of the final.

After replacing the injured Malcolm Marx with flyhalf Handre Pollard, who kicked the game-winning penalty against England, he is their only specialist hooker in the team.

South african rugby team Springboks will face New Zealand's all blacks at the Rugby World Cup finals next Sunday after a narrow win against the England team.
