Defending champions, Zambia, crashed out of the Africa Cup of Nations after a goalless draw with Burkina Faso, who progressed to the quarter-finals.
The Chipolopolo went into the game level on points with Nigeria, who went through to the last eight after a 2-0 win over Ethiopia in the other Group C game.
Zambia will rue weak efforts from Collins Mbesuma and Rainford Kalaba in a poor game against Burkina Faso.
Clifford Mulenga also missed a half-chance late as Zambia limped out.
It is the first time the reigning champions have gone out in the group stage since Algeria in 1990, when there were four groups of three teams.
But Zambia deserved no more than they got as they failed to produce anything like the form that took them to the title last year – even though they leave South Africa unbeaten after three draws.
In contrast, Burkina Faso have shown good moments – most notably their 4-0 demolition of Ethiopia – and finished top of the group on goal difference.
