Munster head coach Anthony Foley makes four changes for his side's Guinness PRO12 clash with Leinster but the big news comes from the bench, as Tommy O'Donnell has been named among the replacements.
After sustaining a hip dislocation in Ireland's World Cup warm-up game against Wales in August O'Donnell makes an earlier than expected return to the match-day squad this weekend.
After successfully completing his return to play protocols for concussion BJ Botha also returns this week and starts next to Mike Sherry and James Cronin in the front row, while Donnacha Ryan is back in the second row after last week's late withdrawal due to illness, joining fellow Tipperary-lock Dave Foley.
The final change in the forwards sees Jack O'Donoghue introduced at openside with Robin Copeland and Captain CJ Stander as they were.
There is only one change to the backline with Tyler Bleyendaal making his second start at 10, and the New Zealander joins Conor Murray in the halfbacks.
The mid-field pairing of Denis Hurley and Francis Saili, and back three of Simon Zebo, Keith Earls andAndrew Conway all remain in situ.
On the injury front Dave O'Callaghan met with the specialist yesterday for an adductor injury and it has been confirmed that the backrow will be side-lined for approximately six weeks.
Munster: Andrew Conway; Keith Earls, Francis Saili, Denis Hurley, Simon Zebo; Tyler Bleyendaal, Conor Murray; James Cronin, Mike Sherry, BJ Botha; Dave Foley, Donnacha Ryan; Robin Copeland, Jack O'Donoghue, CJ Stander Capt.
Replacements: Niall Scannell, Dave Kilcoyne, John Ryan, Billy Holland, Tommy O'Donnell, Tomás O'Leary, Rory Scannell, Lucas Gonzalez Amorosino.
Former Munster player Sean Cronin who will make his 100th appearance for Leinster against his old side after he was named in Leo Cullen's starting XV.
Elsewhere Nick McCarthy is in line to make his first league appearance for Leinster having come off the bench for his full debut in last weekend's Champions Cup game against Toulon.
Zane Kirchner starts at full back with Fergus McFadden recovering from a calf strain to take his place on the right wing and Isa Nacewa as captain from the left.
Luke Fitzgerald partners Garry Ringrose in the centre for the first time with Ringrose making only his second start in the 13 jersey. The young Academy centre was selected to play against the Scarlets in Round 7 but due to an early injury to Rob Keareny in that game he was moved out to the wing to accomodate Ben Te'o who came off the bench.
In the half backs Ian Madigan starts at 10 with Eoin Reddan getting the nod at scrumhalf.
Jack McGrath, Sean Cronin and Tadhg Furlong start in the front row with Devin Toner and Tom Denton in the second row.
Finally in the back row Dominic Ryan starts at blind side flanker with Sean O'Brien making a welcome return from injury at open side. Jamie Heaslip packs down at number 8.
Leinster: Zane Kirchner, Fergus McFadden, Garry Ringrose, Luke Fitzgerald, Isa Nacewa, Ian Madigan, Eoin Reddan, Jack McGrath, Sean Cronin, Tadhg Furlong, Devin Toner, Tom Denton, Dominic Ryan, Sean O'Brien, Jamie Heaslip
