"I don't think that will have a bearing on tomorrow night," he told reporters. "You have two sets of committed players, lots of contact I would imagine, our players know that.

Wales and Ireland have won five games apiece in their 14 previous meetings, but the Dragons have never picked up a competitive win in this fixture.
