Paris Saint-Germain picked up another injury on Wednesday as forward Désiré Doué went off in the second half of their 1-1 draw at lowly Lorient.
Doué clutched his right thigh before being removed on a stretcher in the 61st minute with his hands on his face.
"It was a bit of a strange injury, I don't know yet what his condition is," PSG coach Luis Enrique said. "I hope it is not a serious one, but we must wait and see."
Doué missed several weeks earlier in the campaign with a calf strain while Ousmane Dembélé -- his PSG and France teammate -- was also sidelined several weeks with a hamstring injury.
The Ballon d'Or winner Dembélé returned to the starting lineup as left back Nuno Mendes gave defending champions PSG the lead in the 49th minute with a downward header from a Doué cross. But Lorient hit back two minutes later through Igor Silva's powerful shot.
"The players had almost nothing left in the tank at the end," Lorient coach Olivier Pantaloni said.
PSG were not punished for their dropped points, however, as Marseille conceded six minutes into stoppage time in a 2-2 home draw with Angers.
Victory would have moved Marseille into first place on goal difference. That looked likely after 18-year-old forward Robinio Vaz came on in the second half to score twice. But Angers defender Ousmane Camara punished Marseille for dropping deep in the closing stages.
The draw allowed Monaco to leapfrog Marseille and go up to second following a 5-3 win at Nantes.
