Nigeria coach Gernot Rohr has confirmed striker Samuel Kalu is fully fit to play in Wednesday's second Group match against Guinea at the Africa Cup of Nations.
Kalu collapsed during training last week due to severe dehydration.
The Bordeaux player was rushed to hospital on Friday and missed the 1-0 win over Burundi on Saturday in the opening match in Group B in Alexandria.
"The very good news is that Kalu did again yesterday in Cairo an MRI and it is now 100% sure that he is fit and he will be available for the game," Rohr said.
"He already started training with the team so we are happy about that because everybody was a little bit scared when this happened."
