A first-half goal from Ademola Lookman was enough to see Nigeria overcome Angola and reach the semi-finals of the 2023 Africa Cup of Nations.
The 1-0 scoreline flattered Angola, who were second best for long periods of the game in Abidjan.
Victor Osimhen saw a 75th-minute header ruled out for offside by the Video Assistant Referee, while Calvin Bassey should have done better when heading over from close range.
Angola’s best chance fell to Zine, who rolled the ball against the base of the post when clean through on goal just before the hour mark.
Nigeria will now face the winner of Saturday’s quarter-final between Cape Verde and South Africa (20:00 GMT) in the last four next Wednesday.
