Stade FranÃ§ais held on for a valuable Top 14 win over Bordeaux-BÃ¨gles on Saturday despite seeing skipper Sergio Parisse sent off in the first half.
Clermont ran seven unanswered tries past Mont-de-Marsan for a predictable easy win while Racing MÃ©tro scraped to a narrow win at home to Bayonne.
Elsewhere, Grenoble maintained their unbeaten record on home soil with victory over Agen.
In the late game, Biarritz battled their way to a try-less win over Castres.
Earlier in the day, league leaders Toulon put on an impressive display to thump Montpellier.

Stade FranÃ§ais claimed the spoils in a game rife with controversy although the hosts deserved to win.
Italy skipper Sergio Parisse is in danger of missing next weekend's Six Nations clash with Wales after being sent off late in the first half for allegedly insulting referee Laurent Cardona.
Stade FranÃ§ais led 24-6 at half time but the last of their three tries, scored just before the break, was scored after the Parisians took a quick throw-in with the wrong ball, which the referee failed to notice.
Julien Rey's second half try for UBB was too little, too late as home scrum-half Julien Dupuy's 100 percent record from the kicking tee kept the scoreboard ticking for Stade FranÃ§ais.

Racing MÃ©tro 15-10 Aviron Bayonnais
Stade Yves Du Manoir - Colombes (Paris)
