Former “7th Heaven” star Geoff Stults has been cast alongside Michael Clarke Duncan in the spinoff of Fox’s “Bones.”

Stults will play “Walter Sherman” — aka “The Locator” — an ex-military policeman who can find anything.

Duncan will play Walter’s partner, Leo, a tough cowboy philosopher.

The spinoff, which doesn’t yet have an official title, is based on “The Locator” books written by Richard Greener.

“Bones” is in its sixth season and stars Emily Deschanel and David Boreanaz as a no-nonsense forensic anthropologist and an FBI agent who team to solve crimes.
