The Welsh region travel over the Severn Bridge in confident mood following their opening two victories in the competition this season.
They kicked off their campaign with victory in Italy against I Cavalieri Prato and then retuned to Rodney Parade to beat Perpignan the following weekend.
Their hosts on Sunday sit one-place and just three points below them in the Pool. The English premiership side pushed Perpignan all the way in France in their opening encounter before eventually going down 15 v 12.
They then returned home to beat I Cavalieri Prato which now sets up two cracking games against the Dragons over the next two weekends.
