The crowd at Stade Jean Dauger witnessed a true battle but were not treated to much high-quality rugby. Toulon will have to settle for two points in game they could have won at the death while Bayonne have yet to score a try this season.
Bayonne led 9-6 at half time and the scores were locked at 9-9 soon after the restart when Toulon fly-half Julien Humora added his third penalty in reply to Benjamin Boyet's three, all of which came within the first half-hour.
Boyet edged the Basques in front just after hour mark when his kicked bounced over off the upright. Dumora drew Toulon level with just three minutes left before Benjamin Lapeyre missed what would have been a match-winning penalty after the final hooter.
Biarritz Olympique 18-23 Castres Olympique
Parc des Sports d'Aguilera, Biarritz
Things go for bad to worse for Biarritz, who are still winless. Castres by contrast are the only team to win away from home on Friday.

USA Perpignan 12-9 CA Brive Corrèze
Stade Aimé Giral, Perpignan
Perpignan missed two golden chances to score in the first half leaving the teams all-square at 6-6 at the break.
The pattern continued in the second half and Mathieu Bélie levelled the scores again (9-9) on the hour to match Jerome Porical's three penalties.
A Porical penalty three minutes from time handed the hosts victory.
SU Agen 24-18 Lyon Olympique
Stade Armandie, Agen
Lyon led 13-9 at half-time thanks to a try from wing Franck Romanet.
A ding-dong battle saw Lyon's other wing Remy Grosso score the game's second try but Agen moved 21-18 in front with ten minutes to go as South African fly-half Conrad Barnard and his replacement Valentin Courrent kept the scoreboard ticking as the hosts maintained the pressure and forced LOU into mistakes.
Agen climb to provisional second in the standings while Lyon are last, although a losing bonus point represents their fist of the season.

Parc des Sports Marcel Michelin, Clermont Ferrand
