Murphy has been rewarded for his impressive on-field form with a new two-year extension, extending his time at Collingwood until at least the end of 2024.
Yet to play in a loss for Collingwood this season, Murphy is averaging 10.8 disposals and 5.7 spoils per game, proving himself to be a valuable part of the Magpies' defence.
Johnson meanwhile inked a new one-year extension, tying him to the club until at least the end of 2023.
The 24-year-old debuted in Round 18's win over Adelaide after being recruited in the 2021 Mid-Season Rookie Draft. The young forward impressed throughout his time in Collingwood's VFL side, now making his mark with a three goal performance in Round 19's win over Essendon.
General Manager of Football Graham Wright said the club was looking forward to the duo's future at the club, pleased with their output both on and off the field.
“We’re pleased to reward both Nathan and Ash with further opportunity at the Club – they are both on-field talents and off the field they are outstanding individuals and valued teammates,” Wright said.
“Nathan has shown great persistence despite several injury setbacks through the early stages of his career.
Fresh deals for two Pies.

“He’s shown dedication and commitment to his development which has allowed him to improve his game particularly regarding his one-percenters this season. Not only does he offer great versatility across the ground, but his courageous defence makes him exciting to watch.
“Since joining us last year, Ash has worked hard to finetune his craft and he made great progress through his time with our VFL program, rewarded at AFL-level over the last two rounds.
“We are excited about both Nathan and Ash’s futures, and we look forward to seeing their progress and further development as part of our AFL program.”
