Ivan Cleary is expected to confirm that he will not sign a new deal with Penrith, bringing the curtain down on the greatest modern-day dynasty in Australian rugby league.
Cleary is scheduled to speak at press conference on Wednesday afternoon where the Panthers coach is due to announce his future beyond 2027.
The 55-year-old is contracted until the end of next season, but is believed to have told Penrith powerbrokers he does not want to coach beyond that point.
Cleary's son and the club's halfback Nathan is also off contract next season, along with captain Isaah Yeo and representative back-rower Liam Martin.
The Penrith coach, in his second stint at the club, has built one of the most dominant teams in modern times.
Cleary left Wests Tigers at the end of 2018 to coach his son and while they missed the finals in their first season together, the Panthers have only tracked upwards.
They won the minor premiership in 2020 and were beaten in a grand final by Melbourne before claiming four-straight premierships between 2021 and 2024.
Penrith lost to eventual premiers Brisbane in last year's preliminary final.
Cleary's men have tasted defeat just once so far this campaign and sit top of the table heading into a Magic Round meeting with St George Illawarra on Sunday.
It is unclear what Cleary will do beyond this year, but admitted earlier this year that he was sounded out to head up the PNG Chiefs before eventually rejecting their approach.
The Chiefs have since appointed Hull Kingston Rovers coach Willie Peters.
