JACKSONVILLE, Fla. (AP) -- The Jacksonville Jaguars have signed place-kicker Sam Swank, linebacker JoJo Dickson and defensive tackle David Howard. The first-year players will help the Jaguars get through veteran orientation beginning Tuesday. Place-kicker Josh Scobee, linebacker Paul Posluszny and defensive tackles Terrance Knighton and Tyson Alualu will miss the workouts. Scobee (franchise tag) is not under contract. Posluszny (shoulder), Knighton (eye) and Alualu (knee) are recovering from injuries. Cornerback Rashean Mathis and defensive ends Aaron Kampman and John Chick also will sit out the sessions. Howard, a seventh-round draft pick by Tennessee in 2010, has spent time with Oakland and Seattle. Swank has been with Philadelphia, Cincinnati, the New York Giants and the Jaguars since entering the league in 2009. Dickson spent a week in Jacksonville's training camp last year.
