Seattle's Week 1 build is thinning at wide receiver. Bobo is sidelined by concussion, Tory Horton ankle, Cody White shoulder, and Dareke Young hamstring, with Horton practicing fully later in the week. Uchenna Nwosu is ramping up but not yet ready. Seattle has just six WR on the active roster, leaving depth questions for the 49ers defense. Jaxon Smith-Njigba and Cooper Kupp are noted as the players not on the initial injury report.

The Seahawks could lean on practice-squad options Ricky White III, Courtney Jackson, and Tyrone Broden if needed. Tyrice Knight’s knee absence is notable but he looks set to play, a big boost for the defense. Injury updates roll out Thursday and Friday ahead of Sunday’s 1:05 p.m. kickoff at Lumen Field.
