Paddy Wallace, who deputised at out-half for the injured Humphreys in Paris, shows his versatility by moving to the centre in place of Shane Stewart, injured in the second half of that game.
Meanwhile, Leinster and Munster will name their sides for their respective games against Newport and Bridgend tomorrow. Girvan Dempsey is unlikely to feature in the Leinster side which will be named tomorrow morning prior to their departure for Wales and while there is also a doubt about Denis Hickie, Brian O'Driscoll looks likely to be considered for selection.
Munster will announce their side tomorrow afternoon (4pm) following training at Musgrave Park.
Ulster Squad. Bryn Cunningham; James Topping, Paddy Wallace, Jonathan Bell, Tyrone Howe, David Humphreys,
