Number eight Jamie Heaslip is the only new face in the Ireland rugby team for the pivotal Six Nations showdown with Wales at Cardiff's Millennium Stadium tomorrow.
The Lion has recovered from the three vertebrae cracked in Ireland's 18-11 defeat of France on Valentine's Day and replaces Jordi Murphy, who played in the 19-9 win over England.
Heaslip has made a speedy recovery after being kneed in the back by France lock Pascal Pape, who was punished with a 10-week ban.
"I don't personally listen to outside sources. I listen to our trusted medical team and they gave me some very good guidance," Heaslip said. "I live in a little bubble of day to day, week to week, so it makes life easy for me not to look too far down the line."
Ireland will be on the brink of a second Grand Slam in seven years if they overcome Wales, having seen off Italy 26-3 in their opening match.
