Dempsey gives nod to Cooney
Leinster guaranteed themselves a home quarter-final last weekend, so it's no surprise Girvan Dempsey has rung the changes for this evening's game against Ealing Trailfinders.
There are eight changes in all from the side that beat Moseley in Donnybrook.
John Cooney gets the nod at scrum-half ahead of Luke McGrath, Noel Reid comes in to partner Colm O'Shea in the centre, while Andy Boyle starts on the wing in place of Jordan Coghlan.
Jack Conan switches from flanker to No 8 with Tom Denton coming into the second-row and Ben Marshall playing on the blindside.
James Tracy starts in the front-row in place of Bryan Byrne. Dominic Ryan will captain the side.
Leinster eased to a 49-8 win when the sides met in October. The holders have been utterly dominant in Pool 1, having picked up 23 points from a possible 25, while the English side are rooted to the foot of the pool and are also bottom of the Championship.
Leinster A -- D Hudson; S Coghlan Murray, C O'Shea, N Reid, A Boyle; C Marsh, J Cooney; E Byrne, J Tracy, T Furlong; Q Roux, T Denton; B Marshall, D Ryan Capt., J Conan. Reps: P Dooley, B Byrne, J Van Der Flier, L Auva'a, L McGrath, S Crosbie, J Coghlan.
