Dublin - Ireland center Gordon D'Arcy will retire after the Rugby World Cup in October.
D'Arcy made the announcement on Friday in a letter on the website of his province Leinster, for which he's played 260 times since 1998.
He also has 81 caps for Ireland, including in three World Cups, and made two tours with the British and Irish Lions.
"I am so proud, fortunate, and honored to have represented my province and country for 17 seasons, but I am leaving on my terms, which is how everyone would wish to end their professional rugby careers," D'Arcy wrote.
"It is still hard for me to get my head around the fact that I will not be pulling a jersey on again after October."
He made his international debut in the 1999 Rugby World Cup as a replacement against Romania in Dublin, but didn't establish himself until the 2004 Six Nations. That's when he and Leinster teammate Brian O'Driscoll finally came together for Ireland, and took their midfield partnership to a world record 56 starts until O'Driscoll retired after the 2014 Six Nations.
D'Arcy featured in the 2009 Six Nations Grand Slam, and the title last year.
But the 35-year-old didn't make the squad which retained the title this year, and was dropped as a starter by Leinster this season, putting in doubt his hope of crowning a great career at a fourth World Cup.
With Leinster, he won three European Cups and four Celtic Leagues.
