SAO PAULO -- FIFA secretary general Jerome Valcke is returning to Brazil to inspect host cities as the country continues to struggle to finish its stadiums just four months before the tournament begins.
Valcke will visit three venues beginning on Sunday, and will help decide whether the southern city of Curitiba will remain in football's showcase event amid delays in stadium construction.
One of Valcke's stops will be in the jungle city of Manaus, which last week reported the third worker's death in less than a year. The stadium there was expected to be inaugurated this weekend but won't be ready in time.
Five of the 12 World Cup stadiums promised to be completed by the end of last year remain under construction. Six venues were ready for the Confederations Cup last year, and of the other six, only the Arena das Dunas in the northeastern city of Natal has been finished.
The other host cities with unfinished stadiums are Porto Alegre, Cuiaba and Sao Paulo, which will host the opener on June 12. Work in Sao Paulo's Itaquerao stadium was delayed because of a crane collapse that damaged part of the venue and killed two workers last November.
