UFC 137 main card video preview for 'Penn vs Diaz' on Oct. 29 in Las Vegas

Before the big boys get down and dirty at the top of the UFC 137: "Penn vs. Diaz" main card tomorrow night (Oct. 29) in Las Vegas, a group of little guys will wage war on the undercard, as Scott Jorgensen fights on the main card of a pay-per-view for the first time against a debuting Jeff Curran while Hatsu Hioki makes his Octagon arrival against George Roop.

Jorgensen is ready to rock:

"Jeff's my opponent. I'm not looking past him but there's definitely a long-term goal sitting behind Jeff Curran. He's just that first short-term goal step. As long as I stay excited and go out there and fight my heart out and leave nothing but blood, sweat and tears in that cage, I'll come away with victory."

So is Curran, who is eager to prove himself:

"I need to put up or shut up. I need to get out there and do what I know I'm capable of doing or I have to consider other things. That's why I put that pressure on myself. I try to make that known that this is how important this statement is for me."

Hear from the other two after the jump.

Hioki has never been her before but he's ready to kick down the door and have a gay old time:

"It's my first time being here so I am nervous and excited. It's going to be fun. He has a long reach so I must find my range and play the game."

Roop knows what it will take to come away with what will only be a hard-fought victory:

"I'll have to perform the best I've ever performed in order to win this fight due to the caliber of the opponent Hioki is. He's a wizard on the ground, he's a well-rounded fighter, and great standing up. His cardio's definitely not going to be a factor. I'm going to have to fight the best fight I've ever fought in order to win this fight and I will be ready."

Let's hear some predictions, Maniacs. Scott Jorgensen vs. Jeff Curran and Hatsu Hioki vs. George Roop. Who ya' got? And how?
