Just two points separate Edinburgh, in third place in the Celtic League table and Ulster, in fourth place and a win for McCall's team this weekend would see Ulster occupy at least third spot, depending on how Leinster fare away to the Dragons.

Edinburgh Gunners won 13-9 in their last Celtic League game against Cardiff Blues at the Arms Park on 27 January while Ulster recorded a convincing 30 - 13 win over Llanelli last time out at Ravenhill.

Ulster are the Celtic League’s best away team having won four of their six games on the road this season securing 17 league points in the process. The two sides have clashed on eleven previous occasions in all competitions with Edinburgh victorious only once: 19-18 at Ravenhill in the Celtic League on 6 September 2002.

Good Luck Ulster!
