"Having never been awarded the title of Sole Survivor, Hantz and Mariano return to compete for the $1 million prize and one last shot at redemption," the network said in a statement on Thursday. "They will each join a separate tribe of all new castaways at the start of the game, but it is the tribe who will ultimately decide if they will welcome the knowledge of an experienced veteran, or view these former castaways as a threat."

It will be the fourth time competing for Mariano ("Marquesas," ''All-Stars," ''Heroes vs. Villains") and the third for Hantz ("Samoa," ''Heroes vs. Villains").

The other 16 castaways were revealed earlier this week, and include a former NFL player, an Iraq war veteran and a cheerleader. They will be split into two tribes - Ometepe and Zapatera - when the show returns to Nicaragua for the premiere on Feb. 16 at 8 p.m.
