An independent Disciplinary Committee, chaired by Christopher Quinlan (England) and also comprising Bruce Reece-Russel (England) and Iain Goodall (Scotland) had heard the citing lodged by the Citing Commissioner for the match, Alan Mansell (England).
Following an admission of guilt by the player they found that Mr Quinlan had been in contravention of Law: 10.4 (b) - Stamping or trampling: A player must not stamp or trample on an opponent.
A decision on costs will be made in the coming days. Mr Quinlan will be free to play again on Wednesday, 31 January, 2007.
