Super Eagles players will have to undergo Covid 19 tests ahead of the international friendly match against Tunisia.
Reports say some of the Eagles players were assessed before Last Friday’s match against Algeria.
However, all medical tests for players and coaches returned negative.
The next round of tests will take place on Monday.
Last week, the Nigeria Football Federation (NFF) were forced to clarify claims that four players in the camp had contracted the virus before they took on the Desert Foxes.
Ramy Bensebaini’s sixth-minute strike handed Algeria a 1-0 victory.
Gernot Rohr’s men will be hoping for a better result when they take on Tunisia.
