OSPREYS (3rd) v MUNSTER (2nd), Liberty Stadium, 4pm (live S4C/highlights TG4)
Team News: Donnacha Ryan, Tommy O'Donnell and Felix Jones all return from the Ireland camp to start for Munster against the Ospreys on Sunday.
Dave Kilcoyne has also been released for the RaboDirect PRO12 fixture. He is named on the replacements bench with head coach Rob Penney making six changes to the team that beat Zebre 36-8 last time out.
James Downey comes into the side to make his 40th Munster appearance with Casey Laulala drafted into the starting line-up to form a solid centre pairing.
Andrew Conway starts on the right wing in place of Gerhard van den Heever and Ian Keatley shifts from centre to out-half with Cathal Sheridan retaining his place at scrum half.
Jones starts at full-back with Simon Zebo, who has scored four tries in his last three appearances, on the left wing.
There is an unchanged front row as James Cronin, hooker Duncan Casey and BJ Botha keep their starting places.
Dave Foley comes into the team to partner Ryan in the second row with James Coughlan captaining the side from number 8.
O'Donnell and Sean Dougall - making his first start since injuring his ankle against Connacht in December - complete a dynamic back row.
Young Munster clubman Ger Slattery will be hoping for a repeat of last weekend's two-try performance off the bench with Ireland internationals Kilcoyne and Stephen Archer completing the front row cover.
The province's record appearance holder Donncha O'Callaghan and last weekend's man-of-the-match CJ Stander are also named on the bench with Duncan Williams, JJ Hanrahan and Denis Hurley providing the cover for the backs.
Munster face the Ospreys at the Liberty Stadium on Sunday afternoon. The game will be televised live on S4C with updates here.
Meanwhile, tighthead prop Dan Suter will make his first PRO12 start for the Ospreys when they host the Munstermen.
The Welsh region's head coach Steve Tandy has made changes at half-back and in the front five as they look to follow up on last weekend's record-breaking 11-try 75-7 trouncing of Benetton Treviso.
Matthew Morgan and Tom Habberfield come in to form the half-back pairing, while Duncan Jones and Suter gain starts in the front row and Perry Parker comes in for the injured Lloyd Peers (shoulder) at lock.
As well as being without their Six Nations-tied players, the Ospreys also have Andrew Bishop (back), Tom Isaacs (ankle), Tom Smith (knee) and Eli Walker (hamstring) out injured at present.
But they do have a good deal of experience on their bench with the likes of former Wales captain Ryan Jones, Tito Tebaldi, Hanno Dirksen and Richard Fussell all hoping to have an impact.

Pre-Match Quotes: Rob Penney (Munster) - "We've always found it difficult against the Ospreys. They're obviously full of quality Welsh players and they're going to be a very difficult nut to crack at home.
"They embarrassed us a bit there last year (running out 30-15 winners). They dismantled us at scrum time and we really struggled to get any penetration at all.
"So, we're not going there with any illusions of being able to just walk away with a result, we're going to have to go there very well prepared mentally and physically and give it our best shot. If we're able to secure a couple of points out of the game, that would be great."
Steve Tandy (Ospreys) - "This game will be a big step up in intensity from what this young group have experienced in recent weeks, but it's a challenge they are definitely up for.
"It was a good win last weekend (beating Benetton Treviso 75-7), but it's been important to keep people's feet on the ground in training.
"We put together some decent attacking moves, something we've put a lot of work into, but analysing the performance as a whole in the early part of this week we picked up a lot of areas where we need to improve."
