The Nigerian Football Federation confirmed the approval, expressing delight at welcoming the towering 1.98m shot-stopper to their squad.
Born in England to Nigerian parents, Okonkwo previously represented England at youth levels but has now been cleared to wear Nigeria's colors. With 31 matches and 7 clean sheets for Wrexham this season, he could be a contender for the starting goalkeeper position with Nigeria, especially as current keeper Stanley Nwabili is without a club.
