Frederic Piquionne is an injury worry for Monaco after suffering groin pain in the 2-0 victory over Le Mans.
The striker continued his fine start to life at Monaco as he fired his side ahead in the 12th minute at Leon-Bollee on Saturday.
But he was replaced by Mohamed Kallon at half-time after hurting his groin, and the club are now anxiously waiting to discover the extent of the problem.
Piquionne will be sent for scans early this week and coach Laurent Banide will be hoping he is back in action as soon as possible.
Since joining Monaco from St Etienne at the end of January, Piquionne has scored three goals in four Ligue 1 games.
