For the most part, the "Nitro Circus Live" athletes participate in non-contact sports (unless you count the occasional run-in between man and ramp), but during their Russian leg of the tour, the pros will get a taste of what hand-to-hand combat is really like. In this sneak peek of tonight's episode, Aaron "Crum" Sauvage and Erik Roner accept "NCL" creator Gregg Godfrey's challenge to take on a world champion wrestler. Hey, if you can stare into the eyes of a deadly serpent, a human should be a piece of cake, right?

In the clip, the men try to brush up on their skills before meeting their Olympic-level opponent, only to discover they have none. Gregg, who is a former wrestling champ himself, doesn't exactly have faith in his boys, either. "These two morons have zero chance. They're dead," he says, before ushering them into a room to meet their competition...who happens to be a pretty tough-lookin' chick named Alecya Kavelyenka. "We gotta wrestle that?!" Erik asks in disbelief.

"You are going to go from boys to men," Gregg assures them. Now, where's Jolene Van Vugt with the popcorn? This is going to be one helluva fight.

Check out the clip, and see how Erik and Crum stack up against Alecya tonight at 11/10c on MTV2!
