Duncan lasted 67 minutes on the pitch before being replaced by Algerian Rachid Ghezzal.
Donnarumma scored early in the first half, converting beautifully from the penalty spot to give Brescia the lead in the 17th minute.
Fiorentina responded quickly with a goal from Pezzella on 29th minute connecting well a pass from Pulgar.
Fiorentina is currently 13 on the Serie A league table with 31 points after 27 games.
