An own goal by Paris Saint-Germain keeper Salvatore Sirigu held the French champions to a 1-1 draw at Lille on Wednesday in a stalemate that kept Marseille atop Ligue 1 by a single point.
Edinson Cavani put PSG, who were without star striker Zlatan Ibrahimovic, into a 29th minute lead, after good work from Ezequiel Lavezzi down the right.
That left Laurent Blanc's unbeaten side provisionally overtaking Marseille, who were held by the same scoreline by Lorient 24 hours earlier.
But in the 42nd minute Lille were back level after Sirigu's attempt to punch away a corner did not have the desired effect as the ball hit the bar and went into his net.
The match was at Lille's Metropole stadium which staged last month's Davis Cup tennis final.
Earlier, Saint Etienne climbed into third on the back of a 2-0 win at Montpellier with the first half goals scored by defenders Florentin Pogba and Paul Baysse.
"It's a good week so far," said Saint-Etienne coach Christophe Galtier ahead of the upcoming derby with Lyon.
"I don't know how far back we'd need to go to have 29 points after 16 games."
In Corsica, Bastia fans took direct action to show their displeasure after the club's 2-1 home loss to Evian, with a group of around 50 supporters blocking the players and officials' exit.
This eighth loss of the season left them propping up the table on goal difference with 14 points.
On Tuesday, Lorient's Ghana international Jordan Ayew scored a penalty to cancel out Dimitri Payet's opener and salvage a 1-1 draw against his former club Marseille.
Toulouse saw off hosts Nantes 2-1, while Dimitar Berbatov was on the scoresheet as Monaco shrugged off being reduced to 10 men to beat Lens 2-0.
