Commenting on his team selection, Ireland coach Eric Elwood said: "The majority of the team already have the experience of the Six Nations championship behind them. They have worked very well together over the past couple of months especially in the areas of fitness and conditioning.

"We have three very physical games ahead of us in our pool. If we can get a positive result in our opener against Argentina, it will put us in a very good position for the remainder of the championship."
