FIFA will further review the 2018 and 2022 World Cup corruption investigation, putting the status of hosts Russia and Qatar back in question.

The head of FIFA's auditing committee will examine the full 430-page confidential report by American prosecutor Michael Garcia into impropriety during the bid process, reviving a probe which seemed closed one week ago.

Domenico Scala, a Swiss businessman who serves as the soccer body's audit panel chairman, will then decide whether to turn over any evidence to FIFA's executive committee.
