Dana White: Main events to go 5 rounds

Starting soon, all UFC events will end in a five-round fight regardless of whether a title is on the line.

President Dana White confirmed to ESPN.com Thursday the promotion has decided to make all main events five-round affairs, including pay-per-views and shows aired on Spike TV and Versus.

Up to this point, five-round contests have been reserved for title fights.

"From this day forward, as we speak right here, right now, every fight that is a main event that is not a title fight will be five rounds," White said.

The new policy will not have an effect on bouts that have been previously signed off on, such as a light heavyweight fight between Rashad Evans and Phil Davis, which will headline UFC 133 in Philadelphia in August.

White said he felt it was unfair to make the switch on fighters who had already started mentally preparing for a 15-minute fight as opposed to 25 minutes.

"It should be (five rounds)," said White, pertaining to the Evans-Davis fight. "But what I don't want to do to guys is, if we've already signed the bout agreement, you're mentally training for a three-round fight. For us to come back and say, it's a five-round fight, you can't do that to a guy."

According to White, the five rounds will remain in effect even in situations where a fighter pulls out and is replaced on short notice.
