Sierra Leone fought back from 4-0 down away to Nigeria to draw 4-4 in their 2021 Africa Cup of Nations qualifier after a spectacular comeback in Benin City.
It was one of six qualifying group fixtures on Friday for the finals which will now take place in Cameroon in 2022.
In other matches, Chelsea's Hakim Ziyech struck twice for Morocco as they secured a home victory along with Tunisia, Mali, Niger, and South Africa.
Nigeria 4 Sierra Leone 4
The Super Eagles were coasting towards a third win from three in Group L after racing to a 4-0 lead inside the first half hour of their match at home to Sierra Leone.
Everton forward Alex Iwobi scored twice, with his first goal coming in the fourth minute.
Napoli's Victor Osimhen found the net after 21 minutes on his return to Nigeria's team.
Osimhen then set up Iwobi who got his second goal six minutes later and Villareal's Samuel Chukwueze added a fourth, with another assist from Osimhen.
Sierra Leone began their stunning fightback just before half-time when Kwame Quee grabbed what looked to be a consolation goal.
Alhaji Kamara began to stamp his mark on the match. He added a second for the visitors after 72 minutes to make it 4-2.
Mustapha Bundu then added a third for Sierra Leone to make it 4-3 with 10 minutes remaining.
Nigeria were left stunned as Alhaji Kamara completed an astonishing performance by his team with an equaliser four minutes from time.
Nigeria remain top of their group on seven points - with Sierra Leone third, five points adrift. Second placed Benin play bottom side Lesotho on Saturday.

He hit a penalty in the 31st minute and got his second - Morocco's third - just two minutes later.
Debutant Zakaria Aboukhlal scored in the second half to put the result beyond doubt, giving Morocco a comfortable win.
