Penny (calf) was a non-participant at Thursday's practice, John Boyle of the Seahawks' official site reports.
Since coach Pete Carroll told Brady Henderson of ESPN.com on Wednesday that Penny was unlikely to play Sunday in Minnesota, the running back hasn't logged any activity on the practice field this week. Penny has another chance to get in some reps Friday, but if he doesn't he may be destined for a second DNP in a row since straining his calf Week 1.
