RENTON, Wash. -- The Seattle Seahawks have agreed to terms with veteran offensive lineman Alex Barron following Barron's tryout during Seattle's rookie minicamp last weekend.
Seattle announced the agreement with Barron and three others on Tuesday. The Seahawks also agreed to terms with tight end Cooper Helfet, cornerback Donny Lisowski and tackle Andrew Mitchell.
Barron was the 19th overall pick of the St. Louis Rams in 2005 and was a starter for St. Louis through the 2009 season. He spent 2010 with Dallas and was on injured reserve with New Orleans last season.
To clear roster space, Seattle released cornerback London Durham, linebacker Adrian Moten, tackle Jon Opperud and offensive lineman Brent Osborne.
