Is the fifth time Seattle’s charm? Sunday against the San Francisco 49ers will feature the version number five of the Seahawks’ iffy, scrutinized offensive line this season. It’s the arrangement they’ve been looking forward to most. All the attention has rightly been on the Seahawks missing six starters from their defense. Star defensive backs Richard Sherman and Kam Chancellor remain out, Sherman for the season and Chancellor seemingly for at least that long. Coach Pete Carroll says to expect "some clarity" soon on what’s next for Chancellor and Pro Bowl end Cliff Avril, who is on injured reserve. Jeremy Lane may start with newly re-acquired Byron Maxwell at cornerback Sunday against San Francisco. But Saturday the Seahawks added Lane to the injury report as questionable with a new knee injury. Atlanta’s Matt Ryan picked on Lane all Monday night in Seattle’s latest loss. The Seahawks are already missing rookie cornerback Shaquill Griffin to a concussion Sunday. They could start nickel back Justin Coleman at cornerback if Lane can’t play, the bring Neiko Thorpe in to play corner with Coleman at nickel on passing downs.
