The Seattle Seahawks suffered a significant loss on Sunday during their game against the Los Angeles Rams when lead running back Kenneth Walker III sustained a non-contact oblique injury. The incident occurred midway through the first quarter, leaving Walker clutched his left side and falling to the turf. The team listed him as doubtful to return with an oblique injury.

As a result of Walker’s injury, rookie running back Zach Charbonnet was called upon to take over most of Seattle’s carries. Despite being inexperienced, Charbonnet performed well and is expected to be the team’s lead back in Walker’s absence.

This setback has put a damper on the Seahawks’ season, as they were tied for first place in the NFC West at 6-3 before Walker’s injury. Without their star running back, they will need to rely on other players and strategies to maintain their position atop the division.
