Munster and Leinster will be handing out debuts when both sides take to the field in the Guinness PRO12 this weekend.
Munster head hoach Anthony Foley has named his side to face Ospreys in the Liberty Stadium on Sunday with Tyler Bleyendaal, Mark Chisholm and Francis Saili joining academy player Stephen Fitzgerald in making their first PRO12 starts.
Bleyendaal made his debut for the province against Treviso last weekend when coming off the bench after 55 minutes and this week he makes his first PRO12 start joining Cathal Sheridan in the half-backs.
In total Foley makes eight changes to the starting XV for Sunday's round 2 encounter which kicks off at 2.30pm.
In the front row returning international Dave Kilcoyne makes his first appearance of the season scrumming down alongside Mike Sherry and Stephen Archer, while Mark Chisholm will make his debut for the province when he lines out next to Dave Foley. The only change to the backrow sees Robin Copeland introduced at number 8.
Francis Saili has successfully completed all of his return to play protocols and makes his PRO12 debut in joining academy player Rory Scannell in the centre partnership. Scannell's academy colleague Stephen Fitzgerald is another to make his competitive debut and the 19-year-old is named on the wing joining Andrew Conway and Felix Jones in the back three. Jones takes over the captaincy role this week.
Munster: Felix Jones Capt.; Andrew Conway, Francis Saili, Rory Scannell, Stephen Fitzgerald; Tyler Bleyendaal, Cathal Sheridan; Dave Kilcoyne, Mike Sherry, Stephen Archer; Mark Chisholm, Dave Foley; Dave O'Callaghan, Jack O'Donoghue, Robin Copeland.
Leo Cullen meanwhile has announced the Leinster squad to take on Cardiff Blues in the RDS tomorrow (Kick Off: 5.15pm - live on SKY Sports) in the Guinness PRO12.
Captain Kevin McLaughlin has failed to come through the return to play protocols in time for the game and as a result Isa Nacewa will captain the side from full back on his first appearance back at the RDS since his return from a coaching position with the Auckland Blues.
Nacewa also stands to cross the 400 point mark for Leinster on Saturday evening should he successfully convert any opportunities that comes his way from the tee or from play with the Auckland native currently on 399 points for Leinster. Nacewa is in fifth position on the all-time Leinster points scorers list.
Elsewhere there is only one change to the back line that featured in Meggetland last Friday. Fergus McFadden again starts on the left wing but on the right wing UCD club man Garry Ringrose will make his debut for Leinster having been an unused replacement in last week's game against Edinburgh.
The 20-year-old Academy player was a mainstay in Nigel Carolan's Ireland Under 20s team that competed in last season's Six Nations and World Rugby Championship.
Noel Reid and Ben Te'o get another chance to impress in the centre, while St. Michael's schoolmates Luke McGrath and Cathal Marsh are again selected in the half backs.
The aforementioned McLaughlin is ruled out through injury as is Tom Denton who similarly failed to recover in time having gone through the return to play protocols last week.
Michael Bent, Aaron Dundon and Jamie Hagan will form an experienced front row with Ross Molony coming in for Denton in the second row and Mike McCarthy beside him. It will be Molony's first start for Leinster having played twice last season and having impressed off the bench last week.
The back row consists of Dominic Ryan at blindside, Josh van der Flier for his first appearance of the season at openside and Ireland international Jack Conan once again selected at number eight.
