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

FIFA says American prosecutor Michael Garcia and ethics judge Joachim Eckert want Domenico Scala, the independent chairman of its financial monitoring panel, to study Garcia's 430-page report.

Scala would then recommend details of the confidential dossier for discussion by FIFA's executive committee.

Scala, a Swiss businessman, got the unexpected duty Thursday after Garcia and Eckert met in Zurich, capping a chaotic week for FIFA.

Garcia appealed Eckert's decision last week to close the case against Russia and Qatar.

FIFA's executive committee, including members implicated by Garcia, meets Dec. 18-19 in Marrakech, Morocco.

FIFA says Garcia has formally opened proceedings against some individuals, whom it did not identify.
