Rugby - Team news:With Cardiff Blues due at Thomond Park tomorrow (7.05pm), Munster coach Tony McGahan has made five changes to the side that beat Benetton Treviso last weekend. Ruan Pienaar, meanwhile, will dictate things for Ulster from outhalf when the Ospreys visit Ravenhill tomorrow night (7.05pm).

Four of Munster's changes are enforced, with Ronan O’Gara, Donnacha Ryan and Peter O’Mahony all in the Ireland squad to face Italy and Denis Hurley called up as cover by Declan Kidney.

Hurley’s absence means Felix Jones will start at fullback having returned from long-term injury with a 20-minute cameo against Treviso on Saturday. Ian Keatley will deputise for O’Gara at outhalf, with Tommy O’Donnell in for O’Mahony at the openside and Billy Holland set to partner Mick O’Driscoll in the secondrow.

The final change sees former Ireland international Marcus Horan preferred over Wian du Preez at loosehead prop.

South African Pienaar, no stranger to the position having lined out there for Natal Sharks, will replace Ian Humphreys, leaving the scrumhalf role vacant for Paul Marshall. Otherwise the

Ulster

backline remains the same from the one that began the defeat to Cardiff at the Arms Park last weekend.

There is one change in the backrow, with Pedrie Wannenburg fit again after a foot injury and named at number eight instead of Robbie Diack, while Paddy McAllister comes in at loosehead prop for Callum Black and Andi Kyriacou replaces hooker Nigel Brady.

Ospreyshave also named their team, though doubt remains over replacement Jonathan Thomas, who will be given a chance to prove his fitness after missing the last two weeks with a back injury.

With Brett Wilkinson's involved in the international set-up this weekend, Connachtwill give a first start to Academy prop Denis Buckley when they host former coach Michael Bradley and Edinburgh at the Sportsground tomorrow (7.30pm).

The 22-year-old debuted against Treviso in September and his made an impact off the bench in the four caps since.

Scrumhalf Frank Murphy returns to the starting XV after injury and will replace Paul O'Donohoe.

For Bradley, who spent seven years with Connacht, it will be “business as usual”.

He said: “On a personal level I’ve a lot of fond memories from my time at Connacht and am looking forward to going back but, from a performance perspective, I know exactly how tough it is for teams to take any points away from the Sportground.

“I know the set-up and the side very well and have naturally tried to use that to our advantage as we’ve prepared for this match however our emphasis has, as ever, been on how we need to play to win, rather than on any sort of inside knowledge. When the game kicks off tomorrow it will be business as usual, with our focus fully on coming away with the win.”

Bradley has made four changes to the starting line-up that lost to the Dragons last weekend. Chris Paterson, Jim Thompson and Gregor Hunter will start at fullback, outside centre and outhalf respectively, while Andrew Kelly gets his second start of the season at hooker.
