The governing body has postponed its announcement of ticket pricing for next year's tournament but say demonstrations seen at the Confederations Cup are not linked to the decision
The governing body was scheduled to release pricing details of tickets for next summer's tournament on Monday.
Instead, the announcement will now come on July 19 but, despite Fifa's secretary general Jerome Valcke citing ticketing issues for the delay, it is thought the postponement could be linked to fears the public demonstrations could intensify.
Valcke said: "We want to look at all the issues we have faced at the Confederations Cup.
"We want to avoid having 10,000 tickets that are not collected two days prior to the game."
Meanwhile, the protests continued to grab headlines in the country despite the Selecao winning the Confederations Cup, with rubber bullets and tear gas used by police to combat the marchers.
But Fifa president Sepp Blatter insists the tournament was a "success" on a sporting level.
"Thanks to all those who have helped to make this competition such a success, despite the unrest and protests," he said.
"I am happy to come to the conclusion now, with the sporting results and also — with at least the impression that — the social unrest is now resting. I don't know how long but it is now resting."
Host nation Brazil triumphed at the Confederations Cup, with Luis Felipe Scolari's men beating Spain 3-0 to win their third successive title, and fourth overall.
