The Seattle Seahawks may be without the services of several high-end defenders against the San Francisco 49ers on Thursday Night Football. General manager John Schneider placed outside linebacker Uchenna Nwosu on IR, ruling him out for a minimum of four contests. Rookie defensive tackle Byron Murphy II has also been ruled out. Cornerback Riq Woolen and edge Derick Hall are also at risk of missing out after being sidelined during Tuesday’s practice.
