Paris Saint Germain have been hit by injuries just a week into the new season.
Sammy Traore and Amara Diane both face a spell on the sidelines.
Diane has picked up a groin problem in training and faces up to a month on the sidelines.
The news is a blow for Diane as he had only recently recovered from a knock and his fitness has now suffered another setback.
Traore is still struggling with a thigh problem he sustained in the Super Cup defeat to Lyon at the end of last month.
Both players will miss this weekend's clash with Valenciennes leaving PSG coach Guy Lacombe with a selection headache.
