Diaby red proves costly as Bordeaux beaten by Brive

Bordeaux-Begles could lose ground on Top 14 leaders Lyon after slipping to their second defeat in three matches at Brive.

Mahamadou Diaby's ninth-minute dismissal proved decisive as Christophe Urios' Bordeaux were beaten 30-9, the extra man proving telling for the hosts in the final 15 minutes.

Brive's lead was only 16-9 going into the final quarter of an hour but Julien Blanc and Matthieu Voisin went over to make the points safe on Saturday.

Lyon have a four-point lead over Bordeaux and can stretch that with a win over Clermont Auvergne on Sunday.

Bayonne could have closed the gap on the top two but instead fell to a 20-9 loss at the hands of Toulon.

Defending champions Toulouse's poor start to the season continued at Montpellier – who ran out 33-22 winners thanks to a double from Gabriel Ngandebe and 15 points from the boot of Anthony Bouthier.

Elsewhere, Pau beat Castres 37-24 while struggling Paris clubs Racing 92 and Stade Francais remain in the bottom two after defeats to La Rochelle and Agen respectively.
