FIFA prosecutor Michael Garcia's report into alleged World Cup bidding corruption has been delayed by several weeks.
FIFA says the ethics committee's investigatory chamber expects to submit its report "by the first week of September." In June, Garcia set a target of late July to deliver his confidential report to ethics judge Joachim Eckert.
Eckert will use the investigation file to decide on possible sanctions against nine bidders which competed to host the 2018 or 2022 World Cup. Russia and Qatar won hosting rights in December 2010 votes of FIFA's executive committee.
FIFA President Sepp Blatter has said that only his ruling board, and not Eckert, has power to overturn a vote and order a re-run.
