Argentina international Leonardo Senatore has been cited for biting in the Jaguares' narrow loss to the Sharks in Super Rugby on Saturday.
No. 8 Senatore is alleged to have bitten Sharks flanker Keegan Daniel on the arm in a ruck near the end of the tight game in Buenos Aires. The Sharks won 25-22.
Agustin Creevy, the Jaguares and Argentina captain, was also cited, this time for a dangerous tackle on the other Sharks flanker, Jean Deysel. It resulted in Deysel leaving on a stretcher with a neck injury.
Super Rugby organizing body SANZAAR said the citing commissioner deemed both incidents worthy of red cards and both players must appear at disciplinary hearings.
Senatore faces a minimum ban of 12 weeks if found guilty of biting.
