Matt Giteau landed a touchline conversion after the full-time hooter as Toulon snatched a 19-all draw with Stade FranÃ§ais at the Stade de France on Saturday.
Bayonne clinched two invaluable points in their quest to avoid relegation from the Top 14 by also holding high-flying Clermont to a draw.
It was a good day for travelling teams as Montpellier won on the road to Bordeaux-BÃ¨gles, Racing revived their ailing fortunes in Lyon and Castres got out of jail in Brive.
Toulouse were easy winners at home to Agen meaning they extend their lead at the top of the standings to eight points over Clermont.

Stade Jean Dauger, Bayonne
This is a huge result for Bayonne as it allows them to move four points clear of Basque rivals Biarritz and the relegation zone. Clermont meanwhile extend their unbeaten run to seven games.
Clermont looked to have had the game wrapped up when Anthony Floch landed a late drop goal, but Bayonne replacement back Sam Gerber touched down in the 78th minute before Benjamin Boyet slotted the touch-line conversion to send the local fans wild.
Clermont's immovable defensive wall and an early try from David Skrela had given the visitors a 16-9 lead at half time and they will harbour a number of regrets after controlling the game but seeing Morgan Parra suffer a rare off-day with the boot.

Union Bordeaux-BÃ¨gles 26-30 Montpellier HR
Stade AndrÃ© Moga, BÃ¨gles
Montpellier grabbed victory in the dying moments with push-over try in the 76th minute of an exciting match.
A losing bonus point is enough to see UBB climb a spot to eighth in the standings though they will be bitterly disappointed not to have claimed the scalp of last year's finalists after Blair Connor bagged a brace.
Montpellier recovered from a slow start to hold a slender 13-10 lead at the break in a ding-dong battle.
The result leaves Montpellier in fifth place in the standings and looking good for a play-off spot.

CA Brive CorrÃ¨ze 13-15 Castres Olympique
Stade AmÃ©dÃ©e Domenech, Brive
Brive are becoming experts at being their own worst enemy while Castres continue their trend for squeezing results out of any situation.
Outscored two tries to none and on the receiving end of three yellow cards, les Castrais still managed to claim victory as they punished the hosts' numerous errors.
The result sees Brive gain an incredible eleventh bonus point this season. An illustration of their knack for losing close games is their points difference, which is just -5, but they sit in eleventh place!
Brive led at 8-3 at half-time but fell victim to the metronomic boots of the CO goal kickers, who had the visitors up 15-8 by the 65th minute.
A 79th minute try from replacement Olivier Caisso proved too little too late for Brive.
