The global friendly game, scheduled for May 28 in Port Harcourt, between Nigeria and DR Congo could called off as a result of a fresh outbreak of Ebola in the central African country.
DR Congo declared the outbreak of the Ebola haemorrhagic fever in Bikoro in the northwestern Equateur province on Tuesday.
Of the five samples analyzed, two were found to be positive for Ebola virus serotype Zaire by RT-PCR.
$1m has now been released by the WHO to support DRC contain the latest outbreak with more than 50 experts deployed to help health officials in the country.
There are two confirmed Ebola cases and 17 deaths that are suspected to have been caused by the virus, according to the heath ministry.
The team identified 5 new suspect cases which were then sent forth to National Institute of Biological Research in Kinshasa.
Nigerian authorities were praised for the way they prevented a more devastating Ebola outbreak four years ago.
"One of the defining features of this epidemic is the fact that three health professionals have been affected", Health Minister Oly Ilunga said in a statement.More news: Bank of England holds United Kingdom interest rates at 0.5%
Ngaleto said of all cases so far reported, seven were now in the hospital in Bikoro. The World Health Organization (WHO) recommends that these diseases be ruled out before diagnosis of Ebola virus.
It said they had already arrived in the regional capital Mbandaka, about 150 km away from the affected area.
Ebola is thought to be spread over long distances by fruit bats and is often transmitted to humans via contaminated bushmeat.
"Our country is facing another epidemic of the Ebola virus, which constitutes an global public health emergency", the ministry said in a statement.
The epidemic so far appears to be centred around the village of Ikoko Impenge, near the town of Bikoro.
Nigeria has already stepped up screening processes at this entry points including major global airports in the country to ensure no outbreak is recorded.
Researchers found there was just a small number of so-called "superspreaders" - highly infectious people who infect many others - in West Africa. Without preventive measures, the virus can spread quickly between people and is fatal in up to 90 percent of cases.
