Nigeria played out a 0-0 draw with Sierra Leone at the Siaka Stevens Stadium in Freetown.
The first leg ended 4-4 in Benin after the Super Eagles surrendered a 4-0 lead.
Gernot Rohr opted for a 3-5-2 formation to solidify things at the back.
Kelechi Iheanacho was the first to ask questions after eight minutes, but his effort was saved by Sierra Leone goalkeeper Mohamed Kamara.
Samuel Chukwueze tried his luck at the quarter hour mark, only to see his ball kissing the upright.
The hosts had their glimpse at Nigeria’s goalkeeper Okoye Oduka after 21 minutes through Kei Kamara, but Oduka was up to the challenge.
Alhaji Kamara could have given the hosts the lead just before halftime, but Okoye came to Nigeria’s rescue as the first half ended goallessly.
Six minutes after the break, Chukwueze found Iheanacho whose shot went over.
Iheanacho though he gave Nigeria the lead at the hour mark, but his goal was ruled offside.
