Hosted by TJ Lavin, The Challenge: USA is currently airing its first season on CBS. Viewers have seen former contestants from Big Brother, Survivor, The Amazing Race, and Love Island competing against one another but there have been no cast members from Phil Keoghan’s Tough as Nails on the reality competition series.

Keoghan revealed the reasoning behind the exclusion of contestants of Tough as Nails, per Entertainment Weekly:

“We have plans to eventually do an all-star version of Tough as Nails. So I think that’s part of the consideration, to allow us to be able to. Other shows have had the chance to do that. Amazing Race, Survivor, Big Brother — they’ve all had a chance to do their all-star seasons. So I’m personally pleased that we’re allowed to do a Tough as Nails all stars before something like that would happen.

I think Tough as Nails contestants would compete really well… just because I know the fitness level of Tough as Nails.”

CBS has renewed Tough as Nails through its fifth season, and the episodes have already been filmed. It’s expected to return midseason.

Hosted by Keoghan, The Amazing Race returns to CBS on September 21st. The Challenge: USA currently airs on Wednesday nights.
