Brisbane Broncos skipper Corey Parker will retire from rugby league at the end of 2016, the 34-year-old announced on Monday.
The Broncos veteran had been in talks over a one-year extension, but elected to hang up the boots after 16 seasons with the club.
Parker has spent his entire NRL career with the Broncos after making his senior debut in 2001 as an 18-year-old.
The forward has made 336 appearances in the NRL, more than any other player in his position, while also playing 13 Tests for Australia.
"I have been very fortunate to fulfil a childhood dream to play for the Broncos," Parker said in a statement.
"At some stage all good things come to an end, and 2016 will be the end of my playing career, but the start of my new journey off the field in which I will remain part of the game.
"I'd like to thank my family and close friends, my team-mates and coaches over 16 years, the Broncos' club, members and fans, and the game of rugby league as a whole."
Parker kicked an important goal in the Broncos' 2006 premiership triumph, but was on the losing side in 2015 as they were beaten by the North Queensland Cowboys.
He made his State of Origin debut in 2004 and will play his 18th game for Queensland on Wednesday.
