Ulster have made no less than thirteen changes to their team ahead of their RaboDirect PRO12 semi-final against Leinster this evening.
The big news for the Northern Province is the return from injury of Ruan Pienaar and Rory Best, in what is a massive boost for the team. Pienaar has not played since leaving the field with an injury early on in the Heineken Cup quarter-final game against English club Saracens. Ulster went on to lose that game.
Other changes to the youthful side which went to Munster and got a win last week include Tommy Bowe, Andrew Trimble and Robbie Diack.
The last time the two sides met was two weeks ago in Ravenhill, with Leinster winning 22-20 on the night. The losing bonus point Ulster picked up however was enough to secure their passage into the knockout phase of the competition.
The winner of the game will meet either Glasgow or Munster in the grand final on Saturday May 31st.
Kick off for the game tomorrow is at 7PM in the RDS.
Ulster: Craig Gilroy; Tommy Bowe, Jared Payne, Darren Cave, Andrew Trimble; Paddy Jackson, Ruan Pienaar; Callum Black, Rory Best, Ricky Lutton; Johann Muller (capt.), Iain Henderson, Robbie Diack, Chris Henry, Roger Wilson.
