LEINSTER will be at full strength for tomorrow nights Celtic League quarter-final against Newport at Donnybrook.

They will field their most powerful line-up in the three meetings against Newport in five weeks, the past two in the Heineken Cup.

Star British Lions centre Brian ODriscoll missed the first match at Donnybrook with a shoulder injury and fellow Irish internationals Girvan Dempsey and Denis Hickie pulled out of the Rodney Parade return a week later with Achilles tendon and shoulder injuries, respectively.

All three are fit this time, and prop Emmett Byrne is also expected to play after suffering a back injury.

If he doesnt make it, former British Lion Paul Wallace, recovered from a long standing ankle injury and back with Leinster from Saracens, will step in. It means Leinster field 13 internationals, 12 Irish plus Australian outside half Nathan Spooner.

The other two, lock Leo Cullen and openside flanker Keith Gleeson, brought up in Australia but now returned to Ireland, are A caps.

Newport are still upbeat about their chances of making it third time lucky.

Were very confident with the squad and the game plan, said captain Simon Raiwalui. We dont want to make as many mistakes as we made last time.

The match is being shown live on Eurosport and Newport are opening the club at 5.30pm, erecting giant screens and providing refreshments.

Leinster team: G Dempsey, D Hickie, B ODriscoll, S Horgan, G DArcy, N Spooner, B OMeara, R Corrigan (captain), S Byrne, E Byrne, L Cullen, M OKelly, E Miller, V Costello, K Gleeson. Replacements: A Magro, A Dunne, B Willis, P Coyle, G Hickie, B Casey, T Brennan. Kick-off 7.35pm.
