Locks Tadhg Beirne and James Porter have been listed by Farrell and the back-row is made up of Peter O'Mahony, Josh van der Flier and CJ Stander.
Tadhg Furlong, who missed 11 months of rugby through injury, is listed on the bench.

"I don't believe it for one second," he told a news conference on Friday.
"Look, the boys are very familiar with everyone who is in the Welsh squad. They play against them all of the time. We know what top performers they can be when they are under pressure. They are an experienced side, who have been in both good, and difficult, positions before.
"Within the two camps, we know the truth. That it is going to be a war of attrition. We have not won there since 2013 which says a lot and we are expecting Wales to be 100% at their best. We have played them at their best before and come unstuck. So we will plan accordingly.
"It doesn't really matter what goes on in the papers, or in the news, in the coming days the game will still be the same. Both teams will kick off, try and get into the ascendancy, try and get a foothold in the game, through the areas that does that for them, set-piece, physicality or line-speed. Once that whistle goes, the game is just the same. It means a lot to both sides. It will be a tough old battle."
