South Africa centre Francois Steyn has been cited following an allegation of biting during the World Cup win over Tonga in Lens on Saturday

Steyn, who went on as a replacement, faces an allegation of biting involving Tonga wing Joseph Vaka.

The 20-year-old Natal Sharks star, who played centre in the 36-0 victory over England 10 days ago, is rated among South Africa's brightest prospects.

But his whole tournament could be in jeopardy if he is found guilty of the charge lodged by match citing commissioner Jean-Claude Legendre.

Steyn and the South African management have been informed of the citing, with a disciplinary hearing to be scheduled as soon as practicable.

South Africa are already through to the quarter-finals, with Springboks coach Jake White likely to see Steyn as a key player for a potential last-eight clash against Wales in Marseille on October 7th.
