An Ireland Select XV will take on Connacht at Donnybrook on Thursday (kick-off 6.30pm), followed by Ireland playing France at the Aviva Stadium on Saturday.
In the GUINNESS Summer Series Test against France, the team that will take to the pitch shows ten changes to the one that started in Bordeaux last weekend.
There are six changes in the back-line, one of which is positional. Felix Jones will make his first start for Ireland at full-back and Keith Earls moves from the centre to the left wing.
With Earls moving into the back-three, Gordon D'Arcy comes into the midfield alongside captain Brian O'Driscoll, with the experienced pair making their seasonal debuts for Ireland.
Jonathan Sexton will start at number 10, linking up again with his half-back partner from the recent Scotland game, Tomas O'Leary.
Paul O'Connell and Jamie Heaslip come into the starting pack after impressing off the bench last time out, and Sean O'Brien moves to blindside flanker.
David Wallace will make his first start of the campaign at openside flanker, while back row colleague Stephen Ferris is a welcome addition to the replacements following his recovery from a serious knee injury.
Match tickets can be purchased via the Ticketmaster website here or through their outlets nationwide. You can also buy tickets from the IRFU offices at 10/12 Lansdowne Road (up until 5pm on Friday).
