INGLEWOOD—The Seahawks dropped a close game to the Rams on Sunday, falling 21-19 at SoFi Stadium.

They also lost rookie guard Grey Zabel, the team's first-round pick in this year's draft, to a knee injury in the fourth quarter.

Zabel injured his knee on Kenneth Walker III's 1-yard touchdown run late in the game, and after being tended to on the field by athletic trainers and team physicians, he walked off, with assistance, to the sideline for further evaluation.

The severity of the injury was not immediately known after the game, with Seahawks coach Mike Macdonald saying they'll do tests Monday to learn more.
