Ulster v Edinburgh Ravenhill, 7.30Given their position at the top of the table Ulster are intent on winning a Celtic League and Cup double. Edinburgh's visit to Belfast is not expected to stop their drive, although the Scottish sides are in a battle of their own to earn a Heineken Cup place next season.

Back-rower Roger Wilson has withdrawn from the Ulster team with an ankle injury (ligament damage) but Ulster are hopeful he will be fit for next week's match against Cardiff.

Neil Best is promoted from the bench to the blindside while captain Andy Ward moves to cover the number eight position.

There are a number of changes to the Edinburgh team that faced Neath-Swansea Ospreys as the national players return to Scotland training for their final Six Nations match. In the centre Alistair Dickson moves from the bench to the starting line-up while in the front row Joel Brannigan returns from injury to start at tight head. Guy Perrett, Craig Harrison and Angus Martyn also start.

Ben Fisher and Murray Driver feature on the bench with Alistair Warnock, who returns from injury. Carlo di Ciacca, Tom McGee and Craig Smith are out injured. Too many changes here. The White Knights should charge on.
