Mazraoui was chosen to play for Morocco in the African Cup of Nations qualifying matches against the Central African Republic.
But a statement from the Moroccan Football Federation read: “Coach Mr. Walid Regragui has called up Youssef Belammari to replace Noussair Mazraoui for two matches against Central African Republic.”
Mazraoui has started all but one game for United since joining from Bayern Munich last month.
