CAF Champions League holder ES Setif has given its group-stage qualification chances a boost with two away goals in a 2-2 draw at Raja Casablanca.
In what was billed as the biggest match of the round between the reigning champion and three-time winner Raja, the Moroccan side was forced to come behind twice in front of its own fans.
Mohamed Benyettou scored both goals for the Algerian side, with Yassine Salhi and then Adil Karrouchy keeping the tie alive for Jose Romao's men ahead of the return leg next week.
The two other Algerian clubs in action, USM Alger and Eulma, both came out victorious.
Sfaxien, under the guidance of new coach Paulo Duarte for the first time in continental competition, was Eulma's visitor and ultimately left trailing 1-0, while reigning domestic champion USM Alger beat Kaloum Star 2-1, though it may come to regret conceding an away goal.
Al-Hilal Omdurman of Sudan picked up arguably the result of the day, claiming a 1-0 triumph at Sanga Balende, taking a huge stride towards progression.
In an otherwise unremarkable encounter, record eight-time champion Al Ahly lost 1-0 to a late Mohsen Yajour screamer against Moghreb Tetouan, while its Egyptian compatriot and debutant Smouha lost by the same scoreline to Leopards de Dolisie.
