Leinster head coach Matt O'Connor has made wholesale changes to his starting XV for Sunday's Guinness PRO12 clash with Newport Gwent Dragons at the RDS (3pm).
With 12 Leinster players in the Irish squad to face France, there are nine changes in total from the team that started the final Champions Cup game against Wasps three weeks ago.
Fergus McFadden, Dave Kearney, Jimmy Gopperth, Michael Bent, Kane Douglas and Dominic Ryan are the six players retained from the team that drew 20-20 in the Ricoh Arena.
Richardt Strauss and Tadhg Furlong join Michael Bent in the front row, with Tom Denton partnering Kane Douglas in the second.
The back row is a mix of youth and experience with Dominic Ryan selected at blindside, Jack Conan at eight and Shane Jennings will captain the side from openside flanker in what will be his 203rd cap for the province.
Luke McGrath starts at scrum-half with Jimmy Gopperth outside him at ten. Fergus McFadden has recovered from the rib injury sustained in the Irish Wolfhounds game against the English Saxons and takes his place on the right wing, while Darragh Fanning is selected on the left. Dave Kearney has also recovered from the shoulder injury picked up early in the game against Wasps and starts at full-back for the first time this season.
Noel Reid and Ben Te'o are once again selected at centre having last played together in the 13-22 away win against Cardiff in January. While Te'o went off with a rib injury that day, Reid scored the opening try in a four try bonus point win.
On the bench, John Cooney, who has been on loan at Connacht this season, has been recalled as scrum-half cover with other options limited by international commitments with the Irish senior squad and the Under-20s squad.
Cooney has, to date, made 27 appearances for Leinster since his debut in September 2011 against the Ospreys and has played five times for Connacht this season having recovered from a shoulder injury.
O'Connor also confirmed that Maks Van Dyke's short-term loan deal with Leinster has come to an end and he has returned to South Africa in time for the new Super Rugby season with the Cheetahs. Van Dyk was drafted in as short-term cover at prop and played a number of times for the Leinster A's and against Connacht in the Guinness PRO12.

Earls is another international representative available for selection and the Limerick native will join captain Hurley in the midfield.

In the centre, this season's top try scorer Danie Poolman is named to start outside Dave McSharry who recently committed two more years to the province.
Up front, the front row is boosted by the return of tight-head prop Nathan White who plays his first PRO12 game since October.
Jake Heenan makes his long awaited return since his injury in round one of the competition and starts in a back row with captain John Muldoon and Number 8 George Naoupu.
From the bench Eoghan Masterson and Tiernan O'Halloran are in line to make their season debut while it would be a first cap for outhalf Shane O'Leary if he was called upon.
Commenting on the team selection and the upcoming game, head coach Pat Lam said: "We lost Eoin (McKeon) and Mils (Muliaina) to injury which was obviously a big blow especially on top of the loss of another back row in Willie (Faloon). But with these guys going down, it's good to welcome back Jake (Heenan) and Tiernan (O'Halloran) from long-term injuries.
"This is a huge game for us against a well-coached and quality side in Scarlets. We know they are breathing right behind us and like us, they have top six aspirations. We haven't won on their soil since 2004 and we've never won at Parc y Scarlets. We've challenged ourselves to take it to another level for this block of four games, and it must start with a performance this Sunday."
Connacht: Leader, Adeolokun, Poolman, McSharry, Healy, Carty, Marmion; Buckley, McCartney, White, Roux, Muldowney, Muldoon (Capt), Heenan, Naoupu.
Replacements: Heffernan, Cooney, Ah You, Dillane, Masterson, Porter, O'Leary, O'Halloran.
