Ebosse, who was 24, was declared dead after he was rushed to a hospital at Tizi Ouzou, east of the capital Algiers, where the match took place on Saturday.
He scored the lone goal for his club JS Kabylie in the home match in what turned out to be a 2-1 defeat against USM Alger, on the second day of the tournament.
Fans had started throwing objects from the stands inside the Tizi Ouzou stadium after the match as the players were returning to their changing room.
Ebosse joined JS Kabylie in 2013, and was best scorer in the 2013-2014 championship.
The Algerian interior ministry ordered an investigation to search for the culprit.
