The Seattle Seahawks will be without starting right guard J.R. Sweezy for Sunday's game against Arizona after suffering a concussion last week.
Seattle coach Pete Carroll announced Sweezy was out after practice on Friday. Sweezy suffered the concussion last Sunday against the New York Giants, but the injury didn't surface until Wednesday. Sweezy has started 18 straight games at right guard for Seattle, the one constant on its offensive line this season.
Carroll did not say who would start in place of Sweezy.
Cornerback Jeremy Lane returned to practice on Friday after missing Thursday with an ankle injury. He's listed as probable, along with backup running back Robert Turbin, who also missed practice on Thursday.
