Seahawks CB Cary Williams goes from starter to inactive

SEATTLE -- The 2015 season has taken a turn for the worse for Seattle Seahawks cornerback Cary Williams.

Signed during the offseason as a free agent, Williams started the first 10 games for the Seahawks. But he was benched during the second half of last week's victory over the San Francisco 49ers after allowing a 36-yard completion to tight end Vance McDonald.

Coach Pete Carroll said Williams and cornerback DeShawn Shead would battle for the starting spot in practice this week. It appears now that Shead will start opposite cornerback Richard Sherman.

Williams was not on the injury report all week. The Seahawks signed him to a three-year, $18 million deal in the offseason, but Williams is due no guaranteed money after this season, according to OverTheCap.com.

The Seahawks activated Jeremy Lane this week, and he is active. Marcus Burley is the fourth cornerback in uniform.

Meanwhile, linebacker Bruce Irvin (knee) came into the game listed as doubtful, but he is active and could play a role.
