Reggie Corrigan will earn his 100th cap when he lines up for Leinster in their Celtic League clash with the Cardiff Blues on Saturday.
Crrigan said: "One of my major ambitions for this year was to reach the 100 cap mark with Leinster.
"I've enjoyed many high moments in my career and this is a fantastic honour. We're all looking forward to playing in the RDS and hopefully it will give us a chance to establish a fresh start.
"I'm personally very excited about the move and hopefully we'll start with a win."
The 34-year-old Leinster and Ireland stalwart joins Shane Byrne and Victor Costello in reaching the 100-cap mark and takes his place in the front row alongside David Blaney and Will Green.
Brian O'Riordan comes in for his first start of the season at scrum-half in an otherwise unchanged backline which includes Gordon D'Arcy, Shane Horgan and Denis Hickie. In the pack, Ciaran Potts replaces Eric Miller.
