Cardiff coach Matt Sherratt has described the Irish teams as “slow poison” after another weekend when the Welsh regions were all left feeling sick. All four of them lost in the United Rugby Championship – with the Scarlets, the Dragons and Cardiff all being beaten by opponents from Ireland. The Scarlets lost 26-10 to Connacht, the Dragons went down 49-26 against Ulster, and Cardiff were beaten 33-20 at home to Leinster.
