'Rampage' promises KO

It's been more than two years since Quinton 'Rampage' Jackson has knocked an opponent out. He's intent to put an end to that streak this weekend.

After weighing in right at 205 pounds for his light heavyweight bout against Matt Hamill during Friday's official weigh-in for UFC 130 inside the MGM Grand Garden Arena, Jackson promised to do his best to give the fans in attendance a highlight finish.

The last time Jackson (31-8) recorded a knockout was against Wanderlei Silva at UFC 92 in December 2008.

"It's been awhile since I've knocked anybody out," Jackson said. "You guys know I want to put on a show."

Hamill (10-2) could prove to be a difficult man to finish. He's been stopped only once in his professional career; a TKO loss to Rich Franklin in September 2008.

It is the first time Hamill, who also weighed-in at 205 pounds, will headline a UFC pay-per-view event.

"This is a huge opportunity for my career," Hamill said. "I can promise you one thing -- it's going to be a good fight.

All 20 fighters set to compete at UFC 130 came in on weight, setting the stage for Saturday's pay-per-view event.

Co-main event fighters Frank Mir (14-5) and Roy Nelson (15-5) both came in at an identical 260 pounds.

Nelson, who wore his hair in pigtails equipped with pink, green and white ribbons, drew some laughs from the crowd. The ribbons were worn in support of a program "Going Green for Pink," which encourages the recycling of computer products. A percentage of the program's proceeds are dedicated to breast cancer research.
