Lille kept its unbeaten record in the French league but lost top spot after drawing 1-1 at Nice, while sixth-place Lyon routed Monaco 4-1.
Coach Patrick Vieira's Nice took the lead in the 49th minute thanks to Denmark striker Kasper Dolberg's fine finish as he clipped the ball neatly over goalkeeper Mike Maignan.
But veteran Turkey striker Burak Yilmaz equalised eight minutes later with a powerful shot from Luiz Araujo's cross.
Paris Saint-Germain and Lille, the only side still unbeaten, both have 18 points from eight games but PSG is top with the better goal difference.
In other matches, Reims forward Boulaye Dia scored a hat trick in a 4-0 win at Montpellier, which had two players sent off in the first half, and Bordeaux grabbed late goals in a 2-0 home win against Nimes.
Champions League semi-finalist Lyon has found its goal touch again thanks to the irrepressible Memphis Depay.
The Netherlands forward scored the opening goal and played a part in the next two - one week after creating all three goals in a 3-2 win at Strasbourg.
Also on Sunday, Strasbourg were 3-0 winners over Brest while Metz accounted for Saint-Etienne 2-0.
