Carlow man Ed Byrne also resumes a bench role for Leinster this week.
Ireland and Lions prop Tadhg Furlong will play his first match in a year tomorrow.
Having recovered from a calf issue and been included in the Six Nations squad this week, he's been named to start for Leinster against Scarlets in the Guinness PRO14.
Offaly's Peter Dooley returns to the front row alongside Furlong, Carlow's Ed Byrne fills one of the spots on the bench.
Scrum-half Luke McGrath will captain the defending champions in Wales while teenager Jamie Osborne is in line to win his first cap from the bench.
