In the final weekend of the French Top 16 before the break for the RBS Six Nations, all three Gallic qualifiers recorded wins.
Toulouse comfortably beat Montpellier as expected by 35 points to nine. Stade Francais narrowly beat Castres Olympique 26-19, and Biarritz overcame Beziers 37-3.
In the Zurich Premiership, London Wasps recorded the result of the week as they beat league leaders Bath on their own patch.
The Parker Pen Challenge Cup winners were leading 10-6 at half-time, and withstood intense second half pressure to end the game with the same score.
Gloucester turned on the style to beat Newcastle 36-12 at Kingsholm. The Cherry and Whites scored five tries in a decisive victory.
But the shock result of the weekend came in the Celtic League. Edinburgh's 50-10 loss to Cardiff Blues raised a few eyebrows.
Edinburgh, still reeling from their 33-0 defeat to Toulouse in Round 6 of the Heineken Cup, had no match for the ferocity of the visitors' attack. The Blues tore the Gunners defence top shreds on their way to scoring seven tries.
Wales' only representative in the Heineken Cup quarter-final, Llanelli Scarlets, narrowly lost a top-of-the-table clash 10-9 to Ulster at Ravenhill.
Munster overcame a spirited challenge from Borders, eventually beating the Scottish side 29-21.
Both the Zurich Premiership and Celtic League continue throughout the RBS Six Nations.
