Seahawks WR Jake Bobo (concussion) is inactive for Week 1 against the 49ers.

Bobo was unable to graduate past limited participation this week, as he works his way through the NFL’s concussion protocol. Backup WR Dareke Young (hamstring) is also inactive, which gives rookie WR Tory Horton an opportunity to hog No. 3 WR duties. Seahawks LB Uchenna Nwosu (knee) likewise remained limited all week, which hurts the Seahawks’ pass rush. The Seahawks also declared LB Jared Ivey, LB Connor O’Toole, OL Mason Richman and TE Nick Kallerup inactive for Week 1 against the 49ers.
