Ireland were forced into a late change on Saturday for their Six Nations match against England at Twickenham after replacement back-row Jack Conan was ruled out through illness.
Conan's place on the bench has been taken by Cian Prendergast, who started in Ireland's tournament-opening loss to champions France.
Ireland coach Andy Farrell had already responded to last week's unconvincing 20-13 win over Italy by making several changes to his starting side, with Jack Crowley picked at fly-half in place of Sam Prendergast.
Tadhg Furlong, Jamison Gibson-Park, Tadhg Beirne and Josh van der Flier have also been brought into the starting line-up.
There is one late change to our Match Day Squad.

Both England and Ireland have won one and lost one of their opening two matches, with England now looking to bounce back from last week's 31-20 defeat by Scotland at Murrayfield that ended their 12-game winning streak.
England captain Maro Itoje wins his 100th cap for his country on Saturday, with back-row forward Henry Pollock making his first test start.
