Central will retire the No.10 jersey for the rest of this year.
It was the last number worn by Joel Dark.
Butcher Boys president Heath Anderson said the gesture has been made "out of respect".
Central's reserve grade, under 19s and women's Blues Tag squads intend to play out the remaining two rounds and whatever finals they make next month. Following two weekends off they all restart against Maitland at St John Oval on Sunday.
Anderson said it was a "difficult decision" to make during a "difficult period" for the Butcher Boys, who are continuing to grieve alongside Dark's family and friends.
Dark collapsed on the field while making his first grade debut for Central earlier this month and died five days later in John Hunter Hospital. He was 19.
His funeral was held on Tuesday at his junior home ground in Old Bar.
Coronavirus restrictions meant many Central teammates, coaches and club officials gathered together at Charlestown to watch the service online via livestream.
Central coach Phil Williams said his "thoughts are still with the Dark family" and backed the call not to take the field in firsts again after a "big few weeks".
Williams also said that his team hasn't trained since their last game on September 6 and going out to play now with such limited preparation "wouldn't be doing anyone justice".
The Butcher Boys mentor noted "we're a young club" with only "two or three blokes over the age of 24" so "wellbeing" was a priority.
Some players will opt not to play in the lower grades.
Newcastle RL chief executive officer Matt Harris said he "understands and respects this decision" after "what has been an extremely challenging" time.
"I would personally like to acknowledge and commend the Central club on how they have rallied around their players and football staff during these difficult times," Harris said.
"The support they have shown each other has been astonishing and demonstrates the strong culture that exists within the Butcher Boys football community.
"Our thoughts and well wishes continue to be with Joel's family and friends along with the Central Newcastle committee, players, football staff and supporters."
Central were sitting equal fifth on the ladder with two wins and five losses from seven games this campaign.
Maitland now have the bye in first grade this weekend alongside second-placed Cessnock.
Lakes are at home to Souths at Cahill Oval on Saturday while undefeated leaders Wyong visit Wests at Harker Oval on Sunday.
