The Court of Arbitration for Sport (CAS) has set a date to hear former Fifa executive committee member Amos Adamu appeal his ban for corruption.
The Nigerian will challenge his three-year ban on 4 October.
He was the first Fifa official sanctioned for bribery last November, after a British newspaper alleged vote-trading in the 2018 and 2022 World Cup bidding contests.
Malian Amadou Diakite will appeal against his two-year ban on 19 October.
A third former Fifa executive committee member Tonga's Ahongalu Fusimalohi will have his hearing on 7 November.
Diakite and Fusimalohi reportedly advised undercover reporters from the British newspaper The Sunday Times how to bribe their former Fifa colleagues.
CAS in the Swiss city Lausanne is sport's highest court.
