Munster scrum-half Jack Cullen has been called up to the squad for the remainder of the tournament. Second Row Josh Murphy will take over the captaincy responsibilities.

Ireland will play Wales on Monday at 7.30pm in the fifth-place semi-final which takes place in Stadio Luigi Zaffanella, Viadana.
