CHARLOTTE, N.C. (AP) The Panthers signed free agent center Gino Gradkowski to a three-year contract and re-signed backup quarterback and special teams standout Joe Webb to a two-year deal Thursday.
Gradkowski is expected to back up Ryan Kalil, the team's All-Pro center. He played in 40 games during three seasons (2012-14) for the Baltimore Ravens, starting all 16 in 2013.
Last year he played in three games for the Atlanta Falcons, starting one.
Panthers coach Ron Rivera says Gradkowski gives the team depth at center and guard, and ''you feel very secure that if something were to happen you can plug him in and not lose everything.''
Webb was second on the Panthers with 12 special teams tackles last year and returned eight kickoffs for 178 yards.
