Seattle finished Sunday's shutout win over the Bears minus the services of Marshawn Lynch.
The Seahawks ruled out their workhorse running back with a hamstring injury at halftime. Beast Mode came into Week 3 as a game-time decision because of a lingering calf injury.
Coach Pete Carroll said after the game that the injury is nothing to worry about.
"We've checked it all out, and there is nothing to be alarmed by," Carroll said. "So we'll just have to wait and see."
Lynch amassed just 14 yards off five carries against Chicago's defensive front, his lowest output in a regular-season game since Week 2 of the 2011 season.
In his absence, the Seahawks won their first game of the season.
