Seahawks HC Pete Carroll said WR David Moore will be out "a while" with a shoulder injury suffered in Thursday's practice. Carroll added that Moore won't be ready for Week 1 but gave no timetable beyond that. With WR D.K. Metcalf recovering from knee surgery, Jaron Brown is in line to open the season as Seattle's #2 WR. WR Tyler Lockett figures to dominate targets early on.
