ERC, the tournament organisers of the Heineken Cup and Amlin Challenge Cup, have announced the Rounds 3 and 4 referee appointments.
Peter Fitzgibbon and George Clancy, two more members of Ireland's international refereeing contingent, will also be on refereeing duty when the Heineken Cup resumes next week.
Fitzgibbon will whistle up the Cardiff Blues v Toulouse tie, while Clancy is the man in the middle for London Irish's trip to Brive.
Meanwhile, following a review of Rounds 1 and 2 of the European action by the ERC's Match Officials Committee, Donal Courtney, ERC's Match Officials Performance Manager, has indicated that referees have been asked to be more vigilant in their refereeing of the scrum and tackle areas as well as paying particular attention to obvious obstructions at kick-offs, mauls and lineouts.
In relation to the scrum, referees have been asked to pay particular attention to front rows adhering to the engagement sequence and the correct binding techniques with a view to reducing the current very large number of reset and collapsed scrums.
