The Tennessee Titans have signed veteran duo Gary Guyton and Corey Lynch.
Linebacker Guyton joins the Titans after a nomadic year in his career which has seen him spend brief spells at the Miami Dolphins, Dallas Cowboys and San Diego Chargers.
The 27-year-old spent three years with the New England Patriots before that, establishing himself as a starting inside linebacker.
Lynch, meanwhile, struggled with injury during his rookie season with the Cincinnati Bengals in 2008 and the safety has since played for the Tampa Bay Buccaneers and San Diego Chargers.
