The Al Ahly supporters expressed thier displeasure with Al Ahly's exit by launching bottles at head coach Marcel Koller and the refereeing team after the clash.
According to Yssscores, CAF could look to impose a fine on the Egyptians following the incidents with their supporters at the Cairo Stadium on Friday night.
The report adds that the referee did add the supporters' bottle-throwing incident in his referee's report after the encounter.
Earlier this month, Orlando Pirates, Mamelodi Sundowns and Esperance all fined by CAF for their supporters' behaviour in the quarter-final round.
Former Zamalek star Ahmed Hassan criticised the Al Ahly supporters for their actions after the game.
"This scene is unacceptable to see, especially from the fans of Al-Ahly club; it is not befitting," Hassan said on DMC.
"The scene of throwing bottles at Koller is not appropriate, no matter what, this man has achieved successes with Al-Ahly club; he should enter respectfully and leave with utmost politeness and respect."
"The act of attacking Koller with bottles is unacceptable, and this is not the way of Al-Ahly fans."
