The Panthers are slated to sign Harris to a contract Tuesday, David Newton of ESPN reports.
Harris inks with Carolina in the wake of star defensive lineman Derrick Brown (knee) suffering a potentially season-ending meniscus injury. The 29-year-old Harris figures to contribute at outside linebacker for the Panthers, so he doesn't directly fill the void left by Brown, but he'll work to bolster the team's defensive front against the Chargers on Sunday. Injuries have limited Harris to 19 regular-season appearances over the last two years.
