Majeed Waris and Alhassan Wakaso both suffered relegation in France after Lorient drew 0-0 with Troyes in the promotion-relegation play-off on Sunday.
The points split earned Troyes a 2-1 aggregate success to qualify for next season's Ligue 1.
Waris scored in the first leg but a late strike from 40-year-old midfielder Benjamin Nivet's gave Troyes a one-goal advantage and they held firm to book their place in Ligue 1.
Troyes join Strasbourg and Amiens in Ligue 1, with Jean-Louis Garcia's men bouncing back to the top tier of French football after a single season in Ligue 2.
