The Court of Arbitration for Sport says appeals by three soccer officials banned by FIFA in a World Cup bidding scandal will be heard no sooner than October.

CAS says legal submissions have pushed back cases involving former FIFA executive committee members Amos Adamu, Amadou Diakite and Ahongalu Fusimalohi.

FIFA's ethics committee banned all three, plus three other officials, last November after British newspaper The Sunday Times alleged vote-trading in the 2018 and 2022 World Cup contests.

Their appeals to FIFA were heard in February before they launched appeals at CAS.

Adamu, a former Nigeria sports minister, is challenging a three-year ban for bribery.

Diakite, from Mali, and Tonga's Fusimalohi got two-year bans.
