Nice midfielder Fabrice Abriel is expected to miss at least four weeks of football after sustaining an ankle ligament injury during his side's 2-0 win over Bastia last weekend.
Abriel was taken off during the victory, having collided with defender Sebastien Squillaci, who made what looked to be an inconspicuous challenge.
Medical staff at the club have now confirmed that Abriel will miss important games against Saint-Etienne and Paris Saint-Germain in the coming weeks.
Nice currently hold 11th position in the Ligue 1 table on 38 points.
