The Seahawks were joined by offensive tackle Duane Brown after he returned to the practice field with limited participation on Thursday at Renton's Virginia Mason Athletic Center. Brown sat out of Wednesday's practice with knee and biceps injuries.

Five Seahawks players did not participate in practice, including defensive end Jadeveon Clowney (core/illness), tight end Luke Willson (hamstring), cornerback Shaquill Griffin (hamstring), linebacker Mychal Kendricks (hamstring), and running back Rashaad Penny (knee).

Also a positive change for the Week 15 matchup is that fullback Nick Bellore (quadriceps) who was limited by an injury during Wednesday's practice was upgraded to a full participant on Thursday.

Seattle continues to prepare for Sunday's road matchup in Charlotte against the Carolina Panthers with one final practice tomorrow, where game status will be announced.
