The two Fifa executive committee members allegedly caught up in a World Cup cash-for-votes scandal have been provisionally suspended pending a full hearing next month.
Amos Adamu from Nigeria and Tahiti's Reynald Temarii were trapped by a Sunday Times undercover investigation.
Four other officials - Slim Aloulou, Amadou Diakite, Ahongalu Fusimalohi and Ismael Bhamjee - have also been provisionally suspended from taking part in any football-related activity.
The ethics committee will meet again in mid-November to take a final decision ahead of the World Cup vote on December 2.
Fifa ethics committee chairman Claudio Sulser said: "The decision to provisionally suspend these officials is fully justified and should not be put in question.
"The evidence that has been presented to us today has led us to take this provisional measure, as we considered that the conditions were definitely met to take this decision and we deem that it is crucial to protect the integrity of the 2018 and 2022 World Cup bidding process.
"We are determined to have zero tolerance for any breach of the code of ethics."
