The Oakland Raiders signed free agent guard Jonathan Cooper, who could provide valuable depth at the position.
Cooper, 29, a North Carolina product, was the No. 7 overall selection of the Arizona Cardinals in the 2013 NFL Draft.
Cooper's career has been injury plagued, limiting him to just 46 career games (31 starts) in six seasons. He missed his entire rookie season with a broken leg, and injuries limited him to a combined nine games in 2016 and 2018.
He played two seasons with Arizona (2014-15), followed by single seasons with the Cleveland Browns, Dallas Cowboys and Washington Redskins.
The Raiders will be without guard Richie Incognito, who was suspended for the first two games of the season for violating the NFL's personal conduct policy.
In a corresponding move, the Raiders waived wide receiver Montay Crockett. The team signed the 25-year-old in June.
He has never appeared in an NFL game, despite spending time in the Cardinals, Redskins, Jacksonville and Green Bay organizations.
