CHARLOTTE, N.C. (AP) — The Panthers have announced they have signed guard Fernando Velasco and center Kevin Matthews, giving Carolina some experienced depth on the offensive line heading into training camp.

Velasco has NFL experience, starting 11 games at center for Pittsburgh last season before suffering an Achilles injury. Velasco signed with the Tennessee Titans as an undrafted rookie and spent his first two season on the practice squad. He moved into a starting role in 2012, starting 13 games at center and three at guard.

Matthews is the son of Hall of Fame guard Bruce Matthews. Also an undrafted rookie, he played in 14 games in 2012 but was cut last year in training camp by Washington.

To make room on the roster Carolina waived center Jared Wheeler and linebacker Billy Boyko.
