Good afternoon and welcome to Ultimate Rugby's live coverage of today's Challenge Cup encounter as Grenoble welcome Cardiff Blues to the Stade Leisdiguieres. After only winning 2 of their 5 games so far in the table, Grenoble are unable to advance to the knockout stages but the French side will still look to deny Cardiff from sealing the top spot of the group and bow out on a positive note. After sealing an impressive 104-12 victory last week against Rovigo, Cardiff will hope that their form will carry on and look to snatch the top spot of the group and guarantee passage to the knockout stages. Stay tuned for live updates as we await kick off.

Grenoble have lost four out of five meetings with Welsh opposition in the tournament. The two top try scorers in this season's competition are Grenoble's Laurent Bouchet & Cardiff's Richard Smith (5).
