Edinburgh Rugby and Bordeaux-Begles, joint top of Pool 3 in the European Rugby Challenge Cup, warmed up for their Round 3 ties next Friday with superb domestic away wins against Heineken Champions Cup opposition at the weekend. 

Edinburgh, who now face back-to-back matches against English club Wasps, secured their first success at Irish Independent Park since 2004 by squeezing home 18-16 against Munster Rugby, with Eroni Sau’s second-half try proving the difference. 

Bordeaux-Begles snatched a 34-30 victory at Racing 92, where Semi Radradra followed his try in the 16-16 draw at Edinburgh in Round 2 with a brace in Paris to put his club in fine fettle for successive matches against TOP 14 rivals Agen. 

There were two other domestic wins for Challenge Cup sides over Heineken Champions Cup teams at the weekend. 

In the Guinness PRO14, Cardiff Blues bounced back from their Round 2 loss at home to Leicester Tigers with a thrilling 31-28 victory at Benetton Rugby, where replacement Jason Harries clinched the win with an injury-time try to boost the Blues’ confidence for their Pool 5 back-to-backs with Pau. 

In the Gallagher Premiership, Worcester Warriors tuned up for successive Pool 1 ties against Dragons with a 20-13 home win over Sale Sharks, with Duncan Weir’s 10 points from the boot proving decisive. 

Elsewhere, Pool 2 leaders RC Toulon cruised to a 19-9 win at Pau, where Anthony Belleau continued his excellent goalkicking form with 14 points prior to consecutive ties against London Irish, who grabbed a 27-27 draw at Pool 4 front runners Bristol Bears via a late Stephen Myler penalty. 

Meanwhile, Brive, locked on four points with Stade Francais Paris behind Bristol, edged a 26-21 home victory over the capital club.
