Woods was an important role player for Seattle's defensive line. He started five of 14 games but saw significant playing time, playing more than 50% of defensive snaps in seven games. 

Woods was primarily a run stopper who had 32 tackles, one sack and two forced fumbles. His suspension begins Sunday when Seattle hosts Arizona.
