Kylian Mbappe will sit out one further league game for Paris Saint-Germain
Mbappe, 19, was handed the sanction for lashing out in retaliation at Teji Savanier during a feisty 4-2 win at Nimes on September 1.
Savanier was handed a four-match ban for his role in the incident, a sanction that was also confirmed following appeals by both players, the French Football Federation (FFF) announced.
Mbappe, who is being tipped to win the prestigious Ballon d'Or award in December, notably on account of his performances for Les Bleus in Russia last summer, has served two of his three matches so far.
He did play and score in PSG's Champions League defeat at Liverpool last Tuesday as the suspension does not cover European games.
PSG hold a five-point lead over second-placed Lille after six league games of the season.
