The Football Association must continue their attempts to deal with the fallout from Lord Triesman's downfall after FIFA announced their ethics committee would be investigating alleged comments he made about England rival bidders for the 2018 and 2022 World Cups.
As part of the world governing body's investigation, the FA must provide an official report into the incident.
Triesman stepped down from his roles as FA chairman and 2018 bid chairman following allegations he accused the Spanish and Russian football federations of conspiring in bribery.
The 66-year-old announced his departure on Sunday and was swiftly replaced by Geoff Thompson, the British FIFA vice-president.
Thompson hopes to meet with FIFA president Sepp Blatter and Spanish federation president Angel Villar Llona at the Champions League final in Madrid on Saturday but that will not now be enough to put a full stop on the matter.
A FIFA statement released on Monday evening said: "FIFA can confirm that FIFA secretary general Jerome Valcke has requested the FIFA ethics committee to examine the alleged statements made by Lord Triesman in relation to the bidding process for the 2018 and 2022 FIFA World Cups.
"In addition, FIFA has sent a letter to the Football Association asking the FA to provide a report on this matter, including Lord Triesman's position.
"FIFA will not make any further comment on this matter until it has been dealt with by the FIFA ethics committee."
Spanish football federation secretary general Jorge Perez Arias labelled the idea of his country trying to bribe World Cup referees as "ridiculous", while the head of Russia's bid, Aleksey Sorokin, called for football's governing body to "take appropriate measures".
The England 2018 World Cup bid team faxed letters of apology to both associations as they attempted to minimise the damage caused, while FA board members David Sheepshanks and Roger Burden have been drafted in as acting joint chairmen of the national governing body.
