Griffen (concussion) will play Sunday against Seattle, according to Chris Tomasson of the St. Paul Pioneer Press.
Griffen suffered the concussion last week in a car accident and didn't feature in Week 2 against the Cardinals, but he wasn't listed on the injury report throughout the week and has recovered well enough to be available for Sunday's matchup. He played 41 percent of the defensive snaps in Week 1 against the Bengals.
