Stade Français Paris 20-13 SU Agen
Stade Charléty, Paris
Not much fun to watch in wet condition in Paris, but Stade Français played the better tactical game in an afternoon dominated by kicking.
Agen win Saimoni Vaka scored in the first minute, but the hosts moved in front early in the second half with Julien Arias's try proving decisive.
Racing Métro 16-17 Stade Montois
Stade Yves Du Manoir - Colombes (Paris)
Mont-de-Marsan claim their first win of the season thanks largely to the boot of Antoine Vignau-Tuquet, who kicked the winning penalty in the dying minutes.
Racing led 13-6 at the break with Olly Barkley scoring all the hosts' points but two yellow cards in the second half allowed the visitors to get back into contention.
The result is Racing's fifth consecutive loss.
FC Grenoble 9-6 Aviron Bayonnais

Grenoble maintain their unbeaten record at home and their place in the top six. Bayonne head home with a deserved losing bonus point.
Union Bordeaux-Bègles 13-16 Castres Olympique
Stade Jacques Chaban-Delmas, Bordeaux
A terrible result for UBB, who headed into this clash under massive pressure, as it leaves them stuck in the relegation zone.
In driving rain, the scores were locked at 10-10 at the interval and 13-13 in the 66th minute.
But Rory Kockott landed the winning penalty in the last minute after the home scrum wilted under pressure.
Biarritz Olympique 15-3 USA Perpignan
Parc des Sports d'Aguilera, Biarritz
