Shane Jennings will captain Leinster in their PRO12 clash against the Scarlets at Parc y Scarlets on Saturday.
Jennings is joined in the back-row by fellow flanker Dominic Ryan and number eight Leo Auva'a.Damian Browne locks down alongside Devin Toner.
Isaac Boss, who skippered the side in last weekend's 10-all draw away to Sale Sharks, partners Ian Madigan at half back.
Twenty-three-year-old fly-half Madigan, who was the province's young player of the year last season, will make his 50th appearance after featuring 26 times last season.
Noel Reid continues his centre partnership with Brendan Macken, with Andrew Conway named in a pacey back three alongside Fionn Carr and full-back Isa Nacewa.
Tom Denton could be set to make his competitive debut for the team if he appears from the bench which includes six products from the Leinster Academy.
Meanwhile, the Scarlets are showing their intent with a strong team and plenty of experience and power to call on from the replacements bench.
There will be plenty to excite the home supporters in the backs with Wales internationals Liam Williams, George North and Scott Williams on hand - backed by experienced league campaigners Andy Fenby, Gareth Maule and Aled Thomas - all of whom put in strong performances in their pre-season clash against London Welsh last weekend.
Aaron Shingler returns to the back-row alongside Josh Turnbull and new skipper Rob McCusker at number eight, with new South African signing George Earle and former Osprey Richard Kelly in the second row after the Scarlets produced a strong line-out performance last weekend.
With internationals Matthew Rees, Rhys Priestland and Jon Davies on the bench, the Scarlets have plenty of experience and flair to draw on for this encounter.
Form: Scarlets have begun in round one of the RaboDirect PRO12 with victory in three of the last four years. The Welshmen concluded the last campaign with just one defeat in their last seven matches: 23-26 at Edinburgh on 30 March. Leinster were the only side to beat Scarlets at home in the RaboDirect PRO12 last season. Since the tournament became a season long one in 2003/04 amazingly Leinster have won in round one just once: 23-8 at home to Edinburgh in 2007! The only side to defeat the Leinstermen in the PRO12 after the 2011 Rugby World Cup was Ospreys, who did it twice. Scarlets have not beaten Leinster in their last seven encounters in all competitions, since their 18-16 victory at Parc y Scarlets in the opening round of this competition in season 2009/10.
