Paris, France (SportsNetwork.com) - PSG will be without winger Lucas Moura for at least the next month because of an adductor injury.

Lucas sustained the problem in PSG's 2-2 draw with Caen two weeks ago, and he has not feature since.

The Brazilian has been a key part in PSG's team this season, notching seven goals in 24 Ligue 1 outings. But the injury will keep him out of the side during the month of March, which includes Sunday's clash with Monaco as well as a Coupe de France meeting with the same opponent.

PSG enters the weekend two points back of leaders Lyon, while Lucas will also miss out on the return leg of PSG's Champions League knockout round clash against Chelsea, which sits at 1-1 following the first leg in Paris.
