With Isaac Boss starting for Ulster it doesn't seem to have done his chances of starting against England much good. David Humphreys returns following his elbow injury with Andrew Trimble also available following Ireland duty. The Dragons name Wales squad players Aled Brew, Ceri Sweeney and Gareth Cooper in their starting line-up. But Colin Charvis is on the bench, while lock Ian Gough has been asked to rest by the Wales management. Ulster: B Cunningham, T Bowe, P Steinmetz, P Wallace, A Trimble, D Humphreys, I Boss, J Fitzpatrick, P Shields, S Best, J Harrison (capt), T Barker, N Best, K Dawson, S Ferris. Replacements: S Philpott, B Young, R Caldwell, R Wilson/S Harding, K Campbell, K Maggs, P McKenzie. Dragons: Aled Thomas; Gareth Wyatt, Paul Emerick, Phil Dolman, Aled Brew; Ceri Sweeney, Gareth Cooper; Adam Black, Ben Daly, Jamie Corsi, Luke Charteris, Peter Sidoli, Andrew Hall, Jamie Ringer, Michael Owen (capt).
