Leinster coach Joe Schmidt has revealed that Isa Nacewa will retire at the end of the coming season.
The 30-year-old has been a key player for the club in recent campaigns, playing his part in three Heineken Cup title wins.
Schmidt told the club's official website: "I've known Isa for a number of years. He's universally respected due to the quality of his character, his athleticism, skill and commitment.
"He has been great value for us, not just on the field where he has provided a string of highlights but off the field also, where he has contributed enormously to the development of the players around him.
"He's hugely popular amongst supporters and hopefully they will enjoy a few more outstanding performances from Isa in the coming weeks."
Nacewa has made 116 appearances for the club.
