The bidding process for the 2026 World Cup has been suspended, FIFA's Secretary-General Jerome Valcke has said.
The bidding had been due to begin shortly, with a vote expected in 2017.
The suspension comes amid corruption allegations around the 2018 tournament, awarded to Russia, and the 2022 one, to be held in Qatar.
The scandal has led to the resignation of long-serving FIFA President, Sepp Blatter.
Mr Valcke also responded to claims that he was involved in a US$10m (€8.84m) payment to a disgraced football official, relating to the 2010 World Cup in South Africa - which is now being investigated by US authorities.
He denied any wrongdoing.
"It was not FIFA's money...it was request from the official South African authorities and South African FA, and as long as it was in line with rules, we do it," he said, in his first public comments since the scandal broke out.
"You've decided that after Blatter I'm the head to be cut? Fine...But I'm not responsible".
The transactions are central to a US bribery investigation against football's governing body.
Mr Valcke spoke at a news conference in the Russian city of Samara, a venue for the 2018 World Cup finals.
Speaking alongside him, Russian Sports Minister Vitaly Mutko said he saw no threat to Russia hosting the tournament, insisting that the country's successful bid is in line with the law.
