Before the game, the Warriors coach Zdravko Logarusic had claimed witchcraft was at play after a dead bat was found on the pitch before kick-off.
In the second game of Group A, Mali opened with a 1-0 win over their West African counterparts Burkina Faso.
As the scoreline was the same as the Cameroon one, Mali’s goal was also scored almost at the same time as when the Indomitable Lions found the back of the net.
Siaka Bagayoko scored the goal in the 70th minute as his header was enough to settle the encounter in Yaounde.
Cameroon and Mali are now tied at the top ahead of the second group games.
