The Carolina Panthers signed fifth-round draft choice Gary Barnidge from Louisville on Tuesday. The team did not release terms of the deal. Barnidge, a 6-foot-5, 247-pound tight end, figures to contend for playing time with two other young tight ends: Jeff King and Dante Rosario. Barnidge, a first-team All-Big East selection in 2007, played in 47 games with 29 starts for Louisville.
