CHARLOTTE, N.C. -- The Carolina Panthers added more depth at defensive tackle with the signing of free agent Ian Scott.
The 6-foot-3, 302-pound Scott started 33 games in four seasons with the Chicago Bears before signing a free-agent deal with Philadelphia last year. He missed the entire 2007 season with a knee injury and wasn't re-signed by the Eagles.
Walker and Scott will compete for playing time with projected starters Maake Kemoeatu and Damione Lewis.
