Nigel Owens got tired of the various infractions by the Munster and Toulouse front rows during the two sides' Heineken Cup quarter-final at Thomond Park. He took the two front rows aside to have a word, telling them "You don't like to scrummage? Well if you don't, you're in the wrong position."
He went on to say that the next player he felt was causing problems in the scrum would be going to the bin for ten minutes.
