UFC 135: Jones vs. Rampage is an upcoming mixed martial arts event to be held by the Ultimate Fighting Championship on September 24, 2011 at the Pepsi Center in Denver, Colorado.

The Ultimate Fighting Championship had its first ever event in Denver nearly 20 years prior to UFC 135, but the promotion has not operated a pay-per-view event in the Mile High City since The Ultimate Ultimate in 1995. Zuffa, the UFC’s parent company, was not the owner back then. UFC president Dana White, in an interview with MMAWeekly.com, says that the company has long been on a course to return to Denver, but they wanted to do it the right way. “We knew that we wanted to bring a big exciting card back to Denver, and we finally got it done.”
