The Knights have officially parted ways with embattled coach Adam O'Brien, ending his six-season stint at the club.
Newcastle currently sits in 16th place, two points ahead of the wooden spoon spot with two rounds to play.
The 47-year-old has led the club for 142 first-grade games, winning just under 44 per cent.

Knights CEO Phil Gardner thanked O'Brien for his efforts.
“I would like to thank Adam for his hard work and dedication to our club,” said Gardner.
“Under his leadership, the Knights returned to playing finals football for the first time since 2013, for four out of his six years in charge.
“In 2023, our NRL team finished in fifth place, delivering an unforgettable home semifinal victory in front of a sold-out McDonald Jones Stadium, creating scenes not witnessed in Newcastle for over 20 years.
“In his time at the club, the sold-out sign at McDonald Jones Stadium has been a regular feature.
“Adam will depart after 144 games as Knights Head Coach, sitting second on the all-time list behind Michael Hagan. We wish Adam and Sharyn all the very best for the future.”
A Newcastle statement said Peter Parr, who will soon transition from his role as director of football to CEO, will lead the selection process for the club's next head coach.
It was also confirmed that O'Brien would remain in charge for the club's final two games of this season.
“It has been a wonderful privilege to coach this amazing club,” said O’Brien.
“My immediate feeling is gratitude and pride; it has been an honour to coach the Knights.
“From the moment my wife Sharyn and I drove into the Hunter from Bateman’s Bay, we have immersed ourselves in this rugby league town and we have loved calling Newcastle our home.
“We leave with wonderful memories and friendships, along with the genuine belief the club is on the verge of achieving something special and the time is right for change.”
