CHARLOTTE, N.C. (AP) — The Panthers have agreed to a two-year contract extension with backup linebacker Frankie Luvu.

The 25-year-old Luvu was a key player on special teams for Carolina last season, finishing tied for second on the team in tackles with a forced fumble and a blocked punt. On defense he had eight tackles for loss, 1 1/2 sacks along with a forced fumble and fumble recovery.

Luvu was scheduled to be an unrestricted free agent.

The Panthers also re-signed veteran long snapper J.J. Jansen, the team’s longest-tenured player. The 36-year-old Jansen has been with Carolina since 2009.

The Panthers still have 20 unrestricted free agents.
