ASM Clermont Auvergne 27-13 FC Grenoble
Parc des Sports Marcel Michelin, Clermont Ferrand
An uninspired Clermont unit overcame a slow start to claim another win at home and move to the top of the table.
However, a last minute try from Grenoble prop Kevin Goze denied Clermont the attacking bonus point. It was, however, a quick return to form for the Top 14 favourites, who lost at Stade FranÃ§ais last week.
in wet conditions, two second-half tries from France international number eight Damien Chouly, as well as a first half penalty try, saw them to victory while Grenoble had Australian lock Ben Hand red-carded 16 minutes from time.

Stade Toulousain 31-7 Biarritz Olympique
Stade Ernest Wallon, Toulouse
Toulouse bounced back to form in style - for one half at least - as they crushed rock bottom Biarritz.
Tries from former New Zealand wing Hosea Gear, flanker Gregory Lamboley, Samoan prop Census Johnson and hooker Christopher Tolofua had put Toulouse over the hill and out of sight at the break, leading 26-0.
The second half was a more competitive affair as Toulouse went to sleep and Biarritz pulled a try back through Wales wing Aled Brew before centre Gael Fickou rounded off the four-time European champions' scoring.
Afterwards, Toulouse manager Guy NovÃ¨s claimed the second half was so poor that he was "bored".
