Dual role for Brophy
Robert Brophy has been appointed acting chief executive of the International Rugby Board and acting managing director of Rugby World Cup Limited.
Brophy is currently serving as the IRB's chief financial officer and will begin his new role on February 1.
The Irishman's key responsibility will be to oversee the governing body's core business while the search for a permanent successor to Mike Miller is being conducted.
Miller's 10-year reign at the IRB comes to an end next Tuesday with a leading global recruitment company to be given the task of finding the right replacement.
"Robert has a massive wealth of experience in the organisation and global rugby governance and is highly respected by the staff," IRB chairman Bernard Lapasset said.
"I have every confidence that Robert will provide the continuity, stability and leadership required until a new permanent chief executive takes office."
