PSG were forced to put their Ligue 1 title celebrations on ice after second-placed Monaco overcame Lille on Wednesday. (More Football News)
Luis Enrique's side swept aside Lorient 4-1 after doubles from Ousmane Dembele and Kylian Mbappe, putting the pressure on the chasing Monaco.
Yet Youssouf Fofana's third league goal of the season edged Adi Hutter's team to a 1-0 victory, delaying PSG's inevitable title success – barring a miraculous collapse.
PSG, who also have a two-legged Champions League semi-final with Borussia Dortmund to come in May, are 11 points clear with just four top-flight games remaining.
Having lost just once in Ligue 1 all season, PSG would secure back-to-back top-flight crowns if they overcome Le Havre on Saturday at Parc des Princes.
Though victory appears likely against relegation-threatened Le Havre, the Parisians would still be crowned champions without victory if Monaco fail to win on their visit to Lyon the following day.
Given the clash with Dortmund comes just four days after meeting Le Havre, Luis Enrique may rest the likes Bradley Barcola, Marquinhos, Achraf Hakimi, Vitinha and Warren Zaire-Emery, as he did against Lorient.
While the title remains in PSG's hands, Monaco at least took a step closer to Champions League qualification with victory over Lille, sitting 10 points clear of fifth-placed Nice.
