Ruud will help shore up a linebacking corps that lost David Hawthorne to the New Orleans Saints this offseason. Ruud played nine games for the Tennessee Titans last season before being placed on injured reserve with a groin injury. He played his first six seasons for the Tampa Bay Buccaneers.
Lewis has played the last three seasons in Seattle, primarily as a nickel back and special teams standout. He was the special teams captain in 2010 before a knee injury landed him on injured reserve. The injury lingered into last season when he landed on the physically unable to perform list for the first six games. He appeared in the team's final 10 games.
