Carmine Giovinazzo, Jon Sklaroff Join USA's Graceland

CSI: NY's Carmine Giovinazzo and 24's Jon Sklaroff are heading to Graceland.

Giovinazzo has signed on for a "major recurring role" as Sid Markham, the head of LAPD's Gang Task Force who forms a close bond with Briggs (Daniel Sunjata), according to USA. Markham is more mind than muscle and uses his ability to read people to build relationships, but is also prone to occasional acts of violence.
