MUNSTER (1st) v OSPREYS (2nd), Thomond Park, 7.15pm (live TG4)
Team News: Head coach Rob Penney has made eight changes to the Munster team for Saturday night's RaboDirect PRO12 meeting with the Ospreys at Thomond Park.
Munster have been boosted for the top of the table clash by the return of Donncha O'Callaghan and James Coughlan from the Ireland training camp - O'Callaghan will start in the second row with Coughlan listed among the replacements.
Elsewhere in the forwards, Penney has named a completely different front row as David Kilcoyne, Damien Varley and BJ Botha start with David Foley and David O'Callaghan also coming into the side.
Both Foley and O'Callaghan have most recently been invovled in the Munster 'A' team's British & Irish Cup campaign. Varley captains the province for the second time this season.
In the backs, exciting winger Ronan O'Mahony keeps his place for what will be his first competitive game at Thomond Park.
Ian Keatley comes back in at out-half ahead of last weekend's man-of-the-match JJ Hanrahan who drops back to the replacements.
Duncan Williams starts at scrum half and Felix Jones returns at full-back after a slight ankle sprain which ruled him out of the Glasgow game.
Johne Murphy moves to the right wing in place of Andrew Conway who is suffering from bruised ribs, while the centre partnership of Ivan Dineen and Casey Laulala remains intact.
Corkman Duncan Casey takes his place on the bench and the hooker will be hopeful of making his first league appearance for Munster. James Downey was not considered due to a back spasm.

Stand-in captain Jonathan Spratt, his centre partner Andrew Bishop, out-half Matthew Morgan, lock James King and number 8 Morgan Allen are the only survivors from that game.

Pre-Match Quotes: Ronan O'Mahony (Munster) - "As a young fella growing up I went to Thomond Park to watch a lot of games, playing there for the senior team is going to be pretty surreal and I can't wait for Saturday.
"I'm just going to try to embrace the occasion, the intensity of the game is going to be right up there - a top of the table clash - you can't get any better than that.
"A lot of family will come out and support me, they're big into it and are very supportive. It's great that there are two sets of brothers in the set-up. Barry and I and the Scannells (Niall and Rory in the Academy) all recently lined out for the Munster 'A' team in the British & Irish Cup.
"Our parents are obviously so proud, two years ago when Barry was in Clontarf and I was in Garryowen my father was trying to decide which games to go to, whether to go up to Dublin to see him play or to watch me, so at least with the 'A' team this year he can come out and support both of us!
"I'm just trying to build and keep working on my game. I've grown in confidence from the last couple of matches but you've got to take your opportunities.
"There are nine or ten players who can play in the back-three that are available. With Gerhard van den Heever coming in next week he'll add more competition and Luke O'Dea is close to coming back from injury, but I can't really focus on other players.
"I'm just concentrating on my own game and my own performance, hopefully that will be enough to keep my spot."
Steve Tandy (Ospreys) - "This is without doubt a huge game for us. With 13 of our squad on international duty, the team will have a different dynamic to what supporters are perhaps used to.
"The squad have been working hard this week and we as coaches are really pleased with the effort and in particular, the willingness to learn that the squad's younger players have shown at training.
"Llandarcy has been an exciting place to be this week and everyone is looking forward to the challenge of Thomond Park.??
It's never an easy place to go to, Munster have an enviable history at home and while we are proud of the fact that we are the only non-Irish team to beat Munster there in the Rabo since 2006, it's going to be a tough match.
"They are coming into the game after some very impressive performances and have only lost twice so far this season. While they are looking strong, we are also going into the game off the back of our victory against the Dragons last week.
"We are still working towards the full performance the result has given the squad confidence, we know what we have to do and I believe from the work put in this week that this group can deliver what we ask of them.
"We will go to Thomond Park knowing how strong we can be and hopefully we will do ourselves justice."
