Defending Caf Confederations Cup champions Raja Casablanca's title defence took another blow on Sunday as they fell to a 4-2 defeat at home to Moroccan rivals RS Berkane.
The Green Eagles are yet to win a game in this year's competition and currently occupy bottom place in Group A after three rounds of fixtures.
Hassania Agadir's 2-1 win over Otoho d'Oyo later that same evening - thanks to a brace from Yassine Rami - leaves Raja with a mountain to climb ahead of the reverse fixture against Berkane on the 3rd of March, if they are to reach the knockout stages of this year's competition.
Elsewhere, five-time Caf Champions League winners Zamalek needed a 94th minute goal from Youssef Obama to conjure a 1-1 draw at home to Petro de Luanda in Alexandria.
The White Knights also sit bottom of their group having also yet to win a game.
Three-time CAFCC champions CS Sfaxien were also left frustrated on home soil as they were held to a goalless stalemate by Salitas in Sfax, allowing Tunisian rivals Etoile du Sahel to close the gap atop Group B to one point following their 2-1 win over Enugu Rangers.
