Kevin Rankin

Friday Night Lights alum Kevin Rankin has been tapped for the potentially recurring role of Patrick Jane's brother-in-law, Danny Ruskin, on The Mentalist, a CBS rep confirms.

As we first reported, Rankin's character is a charismatic con man who uses his charm and bravado to mask his anxieties.

"He's a hustler, a con artist, a ladies' man — a cunning ne'er-do-well," creator Bruno Heller told Entertainment Weekly, which first reported the casting. "Through his sister, he has an emotional hook in Jane that he's not afraid to tug at when it serves his nefarious purposes."

Ruskin also blames Jane (Simon Baker) for his sister's death. But he will have to rely on Jane to help him when he is suspected of murder.

Rankin will appear in Season 3's second episode, which is scheduled to air Thursday, Sept. 30 at 10/9c.
