The Fox Network rolled out plans for its new-look Thursday lineup, with the new series “American Grit,” a military-themed competition show, taking the slot leading out from “Bones.” The new lineup bows April 14, when “Bones,” which is in the middle of its 11th season, returns for its spring premiere.

“Starring WWE superstar John Cena, ‘American Grit’ follows 16 of the country’s toughest men and women as they are split into four teams and face a variety of military-grade and survival-themed challenges set in the wilderness of Pack Forest in Eatonville, Wash.,” the network says in its announcement. “Cena and an elite group of mentors from the nation’s most exclusive military units — including Navy SEAL Commander Rorke Denver, Army Sergeant Noah Galloway, Marine Gunnery Sergeant Tawanda ‘Tee’ Hanible and Army Ranger Nick ‘The Reaper’ Irving — will push these fierce competitors beyond their limits. With up to a million dollars of prize money at stake, this is the ultimate test of strength, grit, the human spirit and, most importantly, teamwork.”

“American Grit” comes from Leftfield Pictures and is executive-produced by Brent Montgomery, David George, Adam Sher, Will Nothacker and Jon Kroll, along with Cena.

The “Bones” premiere picks up where the fall finale left off. “The all-new episode, ‘The Death in the Defense,’ finds Hodgins (TJ Thyne) eight weeks into his rehabilitation and forced to navigate life in a wheelchair. Meanwhile, Brennan (Emily Deschanel) and Booth (David Boreanaz) investigate the death of a public defender who had multiple defendants from previous cases with motives to kill her,” Fox says.
