Former Hull and Newcastle forward Hatem Ben Arfa will not be able to play for Nice this season under FIFA rules.
Hull are in talks to sign Aaron Lennon on loan from Tottenham for the rest of the season, Sky sources understand.
The 1-0 loss, which saw Alejandro Bedoya net a 16th-minute winner for the visitors, was Marseille's second league defeat in the space of four days having also gone down by the same scoreline at Lille on Tuesday.
And those back-to-back defeats have seen L'OM slip to fifth in the Ligue 1 standings, two points behind fourth-placed Nantes and eight adrift of Monaco in the third and final UEFA Champions League spot.
Monaco could also move further clear when they play second-bottom Ajaccio on Sunday.
Marseille are also already out of Europe this season after failing to pick up a single point from their first five Champions League Group F matches against Arsenal, Borussia Dormund and Napoli.
