The FIFA presidential election will officially be a four-candidate campaign.
FIFA says its election oversight panel validated the proposed candidacies of four-term president Sepp Blatter and his three rivals.
They are: Michael van Praag of the Netherlands, former Portugal great Luis Figo and FIFA Vice President Prince Ali bin al-Hussein of Jordan.
The election is May 29, with voting by 209 FIFA member federations at their congress in Zurich.
The oversight panel scrutinized the candidates' nomination papers and received integrity checks conducted by the FIFA ethics committee.
