Suspended Fifa vice-president Jack Warner has been reported for allegedly violating his ban, according to Concacaf general secretary Chuck Blazer.
In a letter on Tuesday afternoon, Warner urged members of his Caribbean Football Union (CFU) to vote for current incumbent Sepp Blatter in Wednesday's Fifa presidency election.
The move was a surprise as Warner is currently barred from football-related activities amid a Fifa ethics committee investigation into allegations of bribery, and he had made a counter-claim against Blatter as a result.
But Blazer, who initially blew the whistle on Warner, claims the suspended Concacaf president has also broken the terms of his suspension by speaking out ahead of Wednesday's delegation.
Blazer said: "We have clear evidence of a violation of his (Warner's) suspension and we have reported that to the Fifa secretary general Jerome Valcke."
He added: "He has also been meeting with (Concacaf) members, which is against the rules of the suspension."
Warner had written to fellow CFU members to remind them that they should vote for Blatter when he stands for re-election as the only candidate following the withdrawal of Mohamed Bin Hammam, who has also been suspended.
"At our last meeting we agreed as a union to support the incumbent Joseph Sepp Blatter in his quest to regain the presidency," Warner said in his letter.
"I wish to assure you nothing has changed. Our mandate was set then and despite it all we must fulfil it."
Warner was also adamant that there should be no protest on his behalf on Wednesday.
He continued: "I, Jack Warner, a servant and believer in the principles of this beautiful game do humbly besiege (SIC) you, my brothers and sisters from the Caribbean Football Union to desist from initiating any protest action at tomorrow's Fifa Congress."
