ULSTER v LLANELLI SCARLETS, Ravenhill, 7.30pm (live Setanta Sports Ireland)
Team News: New Ulster boss Matt Williams has made five changes to the team that accounted for the Newport Gwent Dragons last time out.
Williams has opted to bring in team captain Rory Best, Paddy Wallace, Mark Bartholomeusz, Matt McCullough and Tom Court for the Ravenhill tie.
Both Best and Wallace are returning from international duty after coming on as second half replacements in Ireland's 34-13 Six Nations win over Scotland last Saturday.
In the backs, Bartholomeusz starts at full-back with Bryn Cunningham dropping to the bench and Mark McCrea and Simon Danielli keeping hold of the wing spots.
Wallace starts at centre alongside Paul Steinmetz with Ireland 'A' international Darren Cave named as cover on the bench. Isaac Boss retains the number 9 jersey and will play alongside Limavady man Niall O'Connor at half-back.
Returning to the starting line-up in the forwards is Matt McCullough, who recently captain Ulster 'A' and has edged out Neil Best for the number 6 jersey.
Ryan Caldwell and Justin Harrison are named as the second row options with Italian lock Carlo Del Fava, who has escaped a ban after his incident with Wales' Stephen Jones at the weekend, covering on the bench.
In the front row the Australia-born Court is named at tighthead with Bryan Young on the loosehead side of the province's scrum.
Meanwhile, Dafydd Jones has been pressed into the second row as emergency cover for Llanelli's trip to face Ulster.
With Vernon Cooper's hand currently covered in plaster after a training ground mishap and Adam Eustace also injured while Scott MacLeod is unavailable, the back rower has put his hand up to partner youngster Lou Reed in the heart of the engine room.
Eager for game-time, Wales' Dwayne Peel starts at scrum half after being released from the Welsh camp while Alix Popham and Ireland's Simon Easterby will start the game from the bench.

Say What: Stephen Ferris (Ulster) - "Matt (Williams) has said to us that if we think it is on in our 22, we go. Everyone has been asking if we have been practising our offloads. But we're not really. It is just we are practising our support.
"Before the Dragons game, people were making half breaks and there was nobody there. Now, if there is a half break, there are two or three people coming from everywhere to get on to the ball.
"I would take a one-point win now (over the Scarlets). It is so vital for us to get another victory and get the crowd behind us."
Robert Jones (Llanelli backs coach) - "We have seven games left and if we really want to win this competition, which we do, we have to win all seven. It is not a case of going into any of these games thinking maybe we can afford to lose one. Every game matters.
"The win against Glasgow has put us back on track and as far as the disappointments of Europe are concerned I think we have come out the other side.
"We were in desperate need of a mental and physical break after the Heineken Cup and although we have only had one game back since then it has put us on the right footing."
Top Scorers: 2007/08 Magners League - Points: Ulster: Paddy Wallace 32; Llanelli: Rhys Priestland 97; Tries: Ulster: Tommy Bowe, Simon Danielli 2 each; Llanelli: Regan King 7.
