Raiders add former first-round pick Barron

The Oakland Raiders have signed offensive tackle Alex Barron to an undisclosed contract.

Barron, selected by the St. Louis Rams with the 19th overall pick of the 2005 NFL Draft, hasn't played in the NFL since 2010 with Dallas. He signed as a free agent with New Orleans prior to the 2011 season and never played for the Saints after suffering a knee injury, then was in training camp with Seattle last summer.

The 30-year-old Florida State product started 74 of the 76 games he played in during his five-year stint with the Rams. He also played 11 games, starting once, with the Cowboys in 2010.
