Watch: Stoppage-time chaos erupts between Algeria, Austria

It seemed Austria’s terrible mistake would end their World Cup run then and there.

With an Algerian win, Austria would fall to third in the group and be eliminated from the World Cup due to Iran’s higher goal differential

However, Austria would receive late game heroics from substitute Sasa Kalajdzic.

Having just been subbed on following the Mahrez goal, Austria and Kalajdzic had little time to keep their tournament hopes alive.

In the 90+5 Austria seemed to have created a scoring chance to tie the match at the death.

But the opportunity for Philipp Lienhart, with just seconds left, would be skied over the bar, seemingly squandering Austria’s last chance.

Austria, however, would get one final attacking opportunity, with failure ending their World Cup run early.

A last-ditch cross into the box would overshoot the net entirely, finding the head Michael Gregoritsch who just barely managed to keep the ball in play.

Gregoritsch’s header would find itself right in the center of the box.

Kalajdzic, positioned perfectly, struck a header onto net, slotting it perfectly into the bottom right corner and drawing the game level at three.

The match would come to an end following the preceding kickoff, sealing a six-goal thriller and one of the most chaotic finishes to a World Cup match in history.

With the match concluded, the round of 32 has been completely set.

South Africa and Canada will kick-start the knockout stage with their match at 3 p.m. on Sunday.
