The Raiders didn't tender a contract offer to Barnes before the start of free agency, making him an unrestricted free agent. But the team confirmed that Barnes is coming back for a second season.
Barnes signed a one-year deal last year to come to Oakland after four years in Jacksonville. He was expected to compete for a starting left tackle spot with Mario Henderson but broke his left ankle in training camp. Barnes appeared in just six games last season, appearing mostly on the right side of the line.
Henderson allowed an NFL-worst 10.5 sacks last season. Last year's starting right tackle, Cornell Green, is an unrestricted free agent. Green committed 12 penalties and allowed 6.5 sacks in 12 games.
The Raiders previously had hired Clancy Pendergast for the position to replace the retired Willie Brown. But Pendergast left after less than two weeks to take over as defensive coordinator at California.
