Survivor Nicaragua Cast : Meet The Contestant of Survivor : Old vs Young

CBS has unveiled the identities of the 20 contestants who will compete on Survivor Nicaragua : Old vs. Young, the reality series' 21st season, premiering September 15.

Legendary football coach Jimmy Johnson is one of the 20 contestants vying for a million dollars. At 67, Jimmy is the second-oldest Survivor Castaway (after Rudy Boesch).

The two tribes squaring off in Survivor: Nicaragua are divided according to age. The elder tribe Espada, comprises 10 Castaways all older than 40. Competitors in the opposing tribe, La Flor, are mostly in their 20s.

"For the survivors. Nicaragua is going to be a little tougher. There's not a lot of food out there and it's also the start of the rainy season, so they're gonna get wet -- and no matter what, no matter how good a shelter they build, they leak. And when your clothes get wet and you get cold and you wake up the next morning and haven't slept . I think the result is you get a lot of tension," longtime "Survivor" host Jeff Probst says of the new season.
