'Hawks' moves continue

The roster shuffle of the Seattle Seahawks continued with three more players released, including offensive lineman Mansfield Wrotto.

Along with Wrotto, Seattle let go of center Steve Vallos and safety Kevin Ellison on Sunday. ESPN.com first reported the Seahawks also released veteran safety Jordan Babineaux and running back Julius Jones. A team spokesman would not confirm those moves. Jones was Seattle's leading rusher each of the last two seasons.

Wrotto was filling in for injured left tackle Russell Okung during the preseason and his versatility to play guard and tackle appeared to have value. But Seattle completed a trade for Philadelphia tackle Stacy Andrews on Sunday.

The Seahawks also claimed guard Evan Dietrich-Smith and cornerback Nate Ness off waivers.

Offensiveline coach Gibbs suddenly retires: A week before their season begins, the Seattle Seahawks are looking for a new offensive line coach after the sudden retirement of Alex Gibbs.

The veteran coach known for his success with zone blocking schemes stepped down just eight days before the Seahawks season opener against San Francisco.

A team spokesman said the 69-year-old Gibbs was "worn out."

Gibbs was considered one of coach Pete Carroll's key hires as he assembled his staff in the offseason. Intent on using Gibbs' zone schemes in the Seahawks run game, Gibbs was hired away from Houston, where he was an assistant coach with the Texans for two seasons.

"We wish Alex the best in his retirement," Carroll said in a statement from the team. "We're grateful for the time we had with him and we're all better for it."

Gibbs, who joined the Texans in 2008, began coaching in the league with Denver from 1984-87. He assisted with the Raiders (1988-89), Chargers (1990-91), Colts (1992) and Chiefs (1993-94) before returning to the Broncos for his greatest successes, from 1995-2003. He won consecutive Super Bowl championships in 1998 and '99.

Terrell Davis was the NFL MVP in 1998, rushing for 2,008 yards and 21 touchdowns inside Gibbs' blocking schemes.

Jim Mora, whom Seattle fired last winter to clear the way for Carroll's return to the NFL, hired Gibbs on his first coaching staff in Atlanta in 2004. Gibbs left when Mora was fired by the Falcons following the 2006 season. He then spent two seasons out of the league before joining the Texans.
