The Cowboys signed linebacker Keith Rivers to a one-year deal for the veteran minimum Wednesday, DallasCowboys.com reports.
Rivers, 28, played three seasons with the Bengals after being selected ninth overall in the 2008 NFL Draft before missing the 2011 season with an injury. He went on to play for the Giants and the Bills, but spent just one year in Buffalo, making the Cowboys his third team in three seasons. He started a career-low three games during his one season with the Bills in 2014.
