McDougald's injury means more playing time for former Rams starter Maurice Alexander, who could emerge as a legit contender for a starting spot in Seattle's secondary.
The Seahawks are off to Minnesota for their third preseason game of the year Friday against the Vikings at 5 p.m. Seattle time.
Here are some of the major personnel updates from coach Pete Carroll’s final session with the media on Thursday before the team departed.
— Safety Bradley McDougald will not play after suffering a pec strain last week against the Chargers. That likely means a starting safety tandem of Tedric Thompson and Maurice Alexander, with Carroll saying Alexander would play substantially more than he did last week in what was his first game with the Seahawks.
