Seahawks RB Zach Charbonnet Suffers ACL Tear

During an appearance on Seattle Sports radio Monday, head coach Mike Macdonald revealed the unwanted news concerning Charbonnet (h/t ESPN’s Brady Henderson). This is a “significant” injury, per Macdonald. Charbonnet is now set to undergo surgery and begin a lengthy rehab process. An ACL tear occurred in this case, as first reported by Henderson’s colleague Adam Schefter.

The injury limited Charbonnet to just five carries on Saturday night. After his final action of the game, the 25-year-old was evaluated in the medical tent before ultimately heading to the locker room. Kenneth Walker III saw a heavy workload once again afterwards. He will no doubt be counted on early and often in the conference title game and (if applicable) the Super Bowl.

Charbonnet was selected in the second round of the 2023 draft. His arrival came just one year after Walker was drafted in the same round. The two have been key figures on offense during their time together, although struggles in the run game were an issue in 2024. Improvements late in this year’s campaign have helped lead Seattle to its current position, however. As such, losing Charbonnet represents a notable blow for the NFC’s No. 1 seed.

From a financial standpoint, this news could prove to be impactful as well. Walker is set to see his rookie contract expire in March unless a deal allowing to remain in the Emerald City is worked out. Charbonnet, meanwhile, is eligible to sign an extension this offseason. Given the nature of his injury, though, it would come as little surprise if team and player paused any potential contract talks which otherwise would have taken place. As things stand, Charbonnet will enter the 2026 season as a pending free agent.

The UCLA product easily set a new career high this year in carries (184), rushing yards (730) and touchdowns (12). Charbonnet did not make a consistent impact in the passing game with only 20 receptions in 16 games, but he has shown an ability to do so previously. Walker has remained the starting back this season, but Seattle’s rushing attack included Charbonnet to a large extent just as it had in 2023 and ’24. How the team adjusts on Sunday could prove to be a key factor in determining the Rams-Seahawks matchup.
