Nigeria coach Stephen Keshi said he was relieved his side had avoided any further injuries after they thrashed minnows Tahiti 6-1 in their opening game at the FIFA Confederations Cup in Belo Horizonte.
Forwards Victor Moses, Kalu Uche and Emmanuel Emenike were all ruled out by injury before the tournament, while midfielder Ogenyi Onazi missed Monday's game with a knee problem.
Keshi hopes the Lazio player will be available for Thursday's encounter with Uruguay, which is likely to play a significant role in determining whether or not Nigeria progress from Group B.
This victory will give us a big morale.
"There are no (new) injuries to the players, because I've already lost four players," he said.
"With all this journey we've been having, arriving yesterday (Sunday) morning at four o'clock, I'm just happy there's no major problems concerning injuries."
Nnamdi Oduamadi, who scored a hat-trick for the African champions at Estadio Mineirao, said: "This victory will give us a big morale. We'll talk in the group now, do everything the coach says, and we'll see what happens in the second game."
Nigeria's victory took them above Spain on goal difference at the top of Group B.
