Brian O'Meara will make his 100th appearance for Leinster when he lines up for Sunday's Celtic League clash against the Edinburgh Gunners at Donnybrook.
O'Meara follows in the footsteps of stalwarts Shane Byrne, Victor Costello and recently Reggie Corrigan in reaching the landmark.
In other team news, Robert Kearney will line up at full back while recent signing Jonny Hepworth will make his first start for the province when he partners Kieran Lewis at centre.
In the pack, Cameron Jowitt comes in for his first start in the backrow alongside Simon Crawford (number eight) and Keith Gleeson who captains the side.
Speaking ahead of the game with Edinburgh on Sunday, O'Meara said: "It's nice to be in such distinguished company. Sunday will be a proud day for me and my family because I've really enjoyed my time with Leinster and reaching 100 caps means a lot to me personally.
"Playing out-half is a position I enjoy. In the times in which I've played there I think that we only lost one game - away against the Dragons. Out-half is a completely different role, whereas playing at 9 is more workaholic but I'm happy doing a job for the team.
"As a Cork man, I'll never feel like a Dubliner but my affection for both Leinster and Munster as my home province are inter-twined. There have been lots of highlights since joining. Any away win in Europe be it against Northampton, Sale or last year against Bath were obvious highlights, but the home and away ties against Montferrand really stick in my mind.
"Being from Munster, the Celtic League final in Lansdowne Road was special because it's not often that you get 30,000 people at an Interprovincial match. With rugby I find that you can neither look back, nor can you look too far ahead. There have been a lot of good times in the past, but the priority is getting the win on Sunday."
