Based on his last name alone, Marcus Lehman will have no success on Survivor: Gabon this year.

But investment banks jokes aside, the competitor is actually afraid that being a doctor won't make him an appealing candidate to fellow castaways.

Jeff Probst doesn't seem to agree, though. The host told Entertainment Weekly:

''Marcus is a physician, as he likes to remind people. And he is a true leader, an extremely bright guy. He's a hero. He is a huge threat to win the game, for sure. He has looks, he's got smarts, he's probably the fittest guy out there, so he's got a lot of things going for him."
