The incident occurred in the first quarter of Carlton’s loss to Melbourne on Saturday at Marvel Stadium, with Newman sitting out the rest of the contest.
Scans confirmed the extent of the injury, with the 27-year old set to undergo surgery.
“We’re really disappointed for Newy, especially after he worked so hard to get back from elbow surgery after Round 1,” Carlton Head of Football Brad Lloyd told the club website.
“His work rate and professionalism is second-to-none. While this is a significant injury, we have full confidence that Newy’s approach to his rehab will be first-class and we look forward to seeing him back to his best in 2021.”
Newman arrived at Carlton ahead of the 2019 season and was a bright spot for the club in an otherwise disappointing campaign, averaging 21.4 disposals and 6.8 marks from his 20 games.
The 0-2 Blues head to GMHBA Stadium this Saturday night to take on Geelong.
