Paris Saint-Germain, Marseille and Lyon all had to settle for a point on Sunday as the top three in Ligue 1 remained unchanged.
Paris Saint-Germain stay top on goal difference from Marseille after they managed to secure a draw at Montpellier despite having to play with 10 men for 80 minutes.
Mamadou Sakho was given a straight red card for pulling down Gaetan Charbonnier as last man after just 10 minutes. However, it was PSG who went ahead nine minutes before half-time through Maxwell.
Reigning champions Montpellier levelled through Remy Cabella 13 minutes after half-time before they too were reduced to 10 men when Younes Belhanda was sent off for his second yellow card with 26 minutes left.
Fabrice Abriel's late volley rescued a point for Nice from a 2-2 draw after they twice fell behind to Marseille at the Stade Velodrome.
The hosts took the lead just before the break through Andre Ayew before Dario Cvitanich levelled the scores six minutes after the restart.
Mathieu Valbuena, who missed a first half spot-kick, put Marseille back in front but Abriel was on hand two minutes from time to ensure Nice left with a point.
Sloan Privat denied Lyon the chance to go top after his second-half goal earned Sochaux a valuable point from a 1-1 draw.
Maxime Gonalons' goal halfway through the first half put Les Gones on course for the summit.
But the hosts rallied and Privat's cool finish saw Les Lionceaux match 17th-placed Evian on 11 points in their bid to escape the drop.
Bordeaux capped a potentially season-defining week with a thumping 4-0 win at mid-table Lorient.
Francis Gillot's team ended a six-game winless run with a late win over high-flying Toulouse last weekend before strengthening their Europa League tilt in midweek with a 1-0 success over Maritimo.
Sunday night's victory came far more emphatically as first-half strikes from Jussie and Ludovic Obraniak set them on their way before Henri Saivet and Yoan Gouffran added the gloss after the break.
