Cameroon came back from the brink of elimination to scrape past Zambia 3-2 and revive their Africa Cup of Nations campaign amid a slew of comedy goals.
World Cup-bound Cameroon, who fell behind after a Rigobert Song blunder, moved to second in Group D on three points from two matches, one behind Gabon, who were earlier held 0-0 by Tunisia.
Tunisia have two points, one more than Zambia, who will face Gabon on Thursday in the last round of matches.
Victory against Tunisia will secure the Indomitable Lions' place in the last eight, but that game could well have meant nothing had it not been for a defiant – and lucky – fightback.
It took only eight minutes for Zambia to take the lead thanks to the 34-year-old Song, playing in a record eighth continental finals for Cameroon.
Song, who was also at fault for the goal his side conceded to Gabon in their opener, headed a Zambian cross onto his keeper, who only managed to parry the ball towards striker Jacob Mulenga, who tapped the ball home.
Zambia held on until the 68th minute when Geremi managed to keep the ball from going out for a throw in by blasting it crossfield, only for Zambia keeper Kennedy Mweene to flail at it and let it pass under his belly before crossing the line.
Inter Milan striker Samuel Eto'o then recaptured his scoring instinct with perfect timing to put the 2008 runners up ahead.
Eto'o thought he had struck the winner when he fired home a crossed shot from inside the box in the 72nd minute.
Paul Le Guen's side, however, conceded a penalty converted by Chris Katongo in the 81st minute, only for Mohamadou Idrissou, who had started on the bench, to head home with four minutes left from a Geremi cross.
The lively encounter was in sharp contrast to the rain-hit first match between Gabon and Tunisia in Lubango.
The Gabon Panthers dominated throughout but proved too clumsy to snatch their place in the quarter-finals with one game to spare.
With the rain pelting down after the break, Gabon were denied a last-minute penalty when Ammar Jemel brought Daniel Cousin down in the area.
