English referee Wayne Barnes will take charge of the Six Nations clash between Wales and Ireland in Cardiff on March 14.
Barnes will replace Steve Walsh, who World Rugby has withdrawn from the game because of business commitments.
In a further change ahead of the Millennium Stadium encounter, New Zealand's Chris Pollock has been replaced as one of the assistant referees by Frenchman Jerome Garces.
Barnes had initially been appointed as an assistant official for Italy’s game against France on March 15, but Welshman Nigel Owens will now take over from him in that role.
