Manchester City winger, Riyad Mahrez, was on the scoresheet as defending champions Algeria drew 2-2 in Zimbabwe on Monday.
Andy Delort and captain Mahrez gave the Desert Foxes a two-goal advantage in Harare that was halved just before half-time when Knowledge Musona netted.
Algeria coach Djamel Belmadi took off Delort and Mahrez as he made five second-half substitutions within 12 minutes.
But the bold move backfired when Prince Dube equalised eight minutes from time.
The result ensured the Desert Foxes become the third country to book a place at the 2022 Africa Cup of Nations.
Cameroon have an automatic spot as hosts and Senegal secured their ticket thanks to a 1-0 win over Guinea-Bissau on Sunday.
