Dave Boling of the Tacoma News Tribune has that detail and others from Seahawks practice.
Back spasms have sidelined Lynch recently. He participated in a walk-through session Wednesday, but he did not practice later in the day.
The next step will be for Lynch to attempt practicing in consecutive days. The fact that he practiced Thursday without complication stands as an encouraging development for the team.
Seattle listed Lynch as a "limited" participant Thursday.
