Hello and welcome to Ultimate Rugby's live coverage of this Challenge Cup pool 1 fixture as London Irish travel to Stade Leisdiguieres to take on Grenoble. Irish come into this one after last weeks nonchalant victory over Rovigo at Madejski. They know that this Grenoble side will present a much tougher challenge having had an impressive Top 14 campaign to date. Grenoble will be looking to recover from last weeks defeat in Cardiff and tonight's game is a must win for the home side. We can expect a highly competitive and physical affair so stay with us for updates throughout.
