Heaslip seeks payback for controversial Cardiff defeat
Ireland were beaten 19-13 in Cardiff nearly seven months ago, with the Welsh claiming victory after edging in front with a second-half try from scrum-half Mike Phillips that Ireland contest should not have been allowed.
Phillips benefited from a quick throw-in by hooker Matthew Rees that should not have been allowed because it was made with a different ball than the one kicked into touch by Jonathan Sexton.
