The incident was sparked by a foul from Egypt's Mohamed Salah on Senegal's Sadio Mane, followed by another challenge involving Mohamed Hany and Habib Diarra.
Both teams' benches cleared, with coaches needing to be separated amidst pushing and shoving, though no further sanctions were issued beyond the match.
Senegal midfielder Habib Diarra received a booking for his involvement, meaning he would be suspended for the final if his team advanced.
Senegal captain Kalidou Koulibaly was also booked earlier in the match, leading to his suspension for the final, and was later forced off due to a groin injury.
