Glasgow scrum-half Niko Matawalu has been cleared of allegations that he bit Munster opponent Donncha O'Callaghan last weekend.
The reported incident took place during Warriors' RaboDirect Pro12 defeat on Friday.
Glasgow revealed Matawalu had been cleared to continue playing after a three-and-a-half-hour league disciplinary tribunal in Cardiff on Wednesday.
"The committee found, on the balance of probabilities, that while Niko's teeth had come into contact with Donncha O'Callaghan's arm, causing injury, this contact was accidental and therefore not an act of foul play. Accordingly, the citing was dismissed," said a club statement.
"The committee said that they had been impressed with the evidence given by all concerned, including Messrs O'Callaghan and Matawalu, and that they had no doubt that the citing commissioner was right to bring the complaint."
Munster scrum-half Conor Murray was also cleared of elbowing Matawalu.
