Nigeria are close to picking 2018 Fifa World Cup ticket following a 1-1 stalemate with Cameroon in Yaounde.
As such, Nigeria lead Group B with 10 points from four games, six ahead of second-placed Zambia, who visit Algeria on Wednesday.
In a winner takes all group, Cameroon have three points from four games and it’s mathematically impossible to overhaul Nigeria, who had picked a point away in Cameroon.
Gent midfielder Simon gave Nigeria the lead when he latched on to a loose ball to give Nigeria the lead. Chelsea star Victor Moses also struck the bar in the second half.
Cameroon leveled with a penalty 15 minutes from time when Vincent Aboubakar converted after Nigeria goalkeeper Ikechukwu Ezenwa clashed with midfielder Arnaud Djoum.
Cameroon had qualified for six of the last seven World Cup tournaments since reaching the quarter-finals in 1990, last missing out in 2006.
They were stunningly crowned African champions in Gabon this year under the tutelage of Belgian coach Hugo Broos, but have only managed three draws and a defeat in their four World Cup qualifiers.
