The provincial sides will go head to head at the RDS from 15:00 tomorrow afternoon.
Leo Cullen has made twelve changes to his Leinster side following Monday’s disappointing loss to Munster at Thomond Park.
The Leinster boss has restored a raft of big names, with his full internationals available for selection once again following player management protocols.
Unfortunately for Cullen’s side though, there is still no sign of Johnny Sexton, despite the fact that he had been expected to return for tomorrow’s clash.
Isa Nacewa, Ross Byrne and Rory O’Loughlin are the only names to maintain their starting places following the St. Stephen’s Day defeat, with four changes amongst the backs.
Noel Reid, Adam Byrne, Luke McGrath and Garry Ringrose have all been reintroduced to the backline.
There is a complete shakeup amongst the forwards, with eight new names stepping in for the visit of Leinster’s Northern rivals.
Jack McGrath, Seán Cronin and Michael Bent make up the front row, while Devin Toner and Hayden Triggs take the 4 and 5.
Finally, an international back row of Seán O’Brien, Josh van der Flier and Jamie Heaslip round out a strong forward line for Cullen’s side.
