The Ireland internationals are added to a 29-man squad, on the back of Leinster’s 32-6 win over Ulster at the RDS last weekend.

Leinster coach Michael Cheika said: “It's going to be a tough game, we understand how difficult it will be.

“We're very hurt from the match up here (at the RDS in September) when we got beat 18-0.

“We'll just prepare ourselves accordingly so that we aware of what's needed if we're going to have a chance against the European champions in their own back yard.

“Every game is different in this, what would you call it, love story between us and them.

“We've got a lot of respect for them as a team and their players. It's going to be a really good game down there.

“If we get our mentality and get our preparation right, then we're going to be in with a shout.

“If we don't get our mentality right, then we better look out, because they're a good team. You saw that again (against Glasgow) on Friday night.”
