Irish referee Alain Rolland has answered a late call to take charge of Sunday's Six Nations Championship clash between Scotland and France at Murrayfield.
The World Cup final referee replaces New Zealander Paul Honiss, who has flown home due to a serious family illness.
Rolland controlled the World Cup final when South Africa beat England in Paris just over three months ago.
Touch judge appointments for the Scotland game are unaffected, with New Zealander Bryce Lawrence and Japan's Taizo Hirabayashi running the line.
