The bouts will be part of UFC 207, which will take place on December 30th in Las Vegas, Nevada.
Brown (20-15) is coming off a quick, stoppage loss to Jake Ellenberger, while Saffiedine (16-5) was decisioned by Rick Story in his last bout.
Magny (18-5) was taken out by Lorenz Larkin in his last fight, and Hendricks (17-5) lost via UD to Kelvin Gastelum in his previous outing.
So, those are two interesting fights. All four men are in need of a win, particularly Brown, who has gone 1-4 in his last 5 scraps.
UFC 207 will be headlined by a fight between bantamweight champ Amanda Nunes and Ronda Rousey.
