Brisbane captain Corey Parker will retire from the NRL at the end of the 2016 season.
The Broncos have called an 1130 AEST press conference on Monday when Parker will make the call.
The 34-year-old Parker is playing in his 16th season and has amassed 336 games, placing him equal fourth with Brad Fittler on the all-time list for matches played.
Only Darren Lockyer (355), Terry Lamb (350) and Steve Menzies (349) have played more.
Parker is preparing for his 18th State of Origin game for Queensland on Wednesday night.
He has also played 13 Tests for Australia.
