Pichot to take Hoskins's job?
In a statement from the global governing body on Monday, Pichot had been nominated for the post, while Bill Beaumont is set to become the new Chairman of World Rugby after it was announced that he was the only nominee to succeed Bernard Lapasset.
Beaumont, 64, is currently Chairman of England's Rugby Football Union (RFU), a job he has held since 2012 having also worked on the organisation of the 2015 World Cup.
A lock forward in his playing days, Beaumont won 34 caps and led England to a first Grand Slam in 23 years in 1980 before captaining the British and Irish Lions in South Africa that same year.
The 41-year-old Pichot, a former scrumhalf, was one of Argentina's stars when they finished third at the 2007 World Cup in France.
He became a driving force in ensuring the Pumas became the fourth nation in an expanded Southern Hemisphere Rugby Championship along with their fellow semifinalists at last year's World Cup in England - New Zealand, Australia and South Africa.
Both Beaumont and Pichot need to achieve a simple majority of votes cast by the World Rugby council at a meeting on May 11, although this now looks a formality given they are the only nominees for the two posts.
The new chairman and vice-chairman will serve for a period of four years commencing on July 1.
