Having seen just three minutes of action in the Six Nations so far, Paddy Wallace returns to the welcome respite of Ulster rugby, this time at inside centre for the Magner's Celtic League game against Llanelli Scarlets.

Wallace began the last game against the Dragons on the bench but capped the 38-13 win with a try at death and has been rewarded with a starting berth by coach Matt Williams.

Hooker and captain Rory Best also returns for tomorrow night's meeting at Ravenhill.

The current Ireland A halfback pairing of Isaac Boss and Niall O'Connor will start, with Scotland's Simon Danielli lining out on the right wing and Under 20 Grand Slam winner Mark McCrea on the left.

Secondrow Ryan Caldwell and backrow Stephen Ferris, who also featured in the 67-7 drubbing by Scotland A, are named in the pack.

Australian Tom Court will join Best and Bryan Young in the frontrow.

Having been cleared of foul play against Wales in the Six Nations, Italian Carlo Del Fava takes a place on the bench at the expense of Roger Wilson.

Matt Williams will be eager to see his side build on their hugely impressive win over the Dragons and prove that it wasn't a honeymoon result after the Australian's recent arrival at Ravenhill.

Ulster are only a point ahead of Connacht at the bottom of the table, while the Scarlets are six points adrift of leaders Leinster in second place.
