Jeff Probst, the longtime host of CBS's Survivor, has revealed which new castaways he sees not lasting in the upcoming season, Survivor: San Juan del Sur.

John Rocker Might 'Target' Fellow Player Who Recognizes Him on 'Survivor: San Juan del Sur'

Probst spoke with Entertainment Weekly on location one day into the start of Survivor: San Juan del Sur in a new video posted Wednesday. In it, he revealed the new players he thinks won't last very long in the game. The first person he singled out was Jaclyn Schultz.

"I think Jaclyn's in trouble," Probst said. "Only because I just don't think she's got the fire in the belly. I just don't see it." He noted that castaways need to have the fire in them in order to survive all the way to the end of the game.

Probst also said that Baylor Wilson, the youngest contestant this year, may have a hard time.

"Baylor is gonna have to latch onto an alliance," he said. "She's still 20 and she's still naive and she doesn't realize it."

The host also said that brothers Drew and Alec Christy might have trouble relating with some of the older members of their tribes.

"I like Drew and Alec because I like seeing the phases of life," Probst admitted, before adding that even though the young brothers should flaunt "how cool they are," that could get annoying to some older players.

 Asked whether John Rocker's girlfriend Julie McGee might be in trouble, Probst admitted that he initially counted her out. He said that if she can get dirty from the start and prove that she's more valuable to the tribe than just her looks, then she might be kept around longer.

Survivor: San Juan del Sur premieres Wednesday night at 8/7c on CBS.
