Seattle Seahawks starting cornerback Brandon Browner is listed as questionable for Sunday's season opener against the Carolina Panthers. Browner suffered a hamstring injury during practice on Tuesday and did not participate in Thursday or Friday's sessions. Chris Clemons, who tore the anterior cruciate ligament and meniscus in his knee in the wild-card round last year, will not play, and fellow defensive end Cliff Avril is listed as doubtful with a hamstring injury.
