The majority owners of Ultimate Fighting Championship have agreed to buy their biggest mixed martial arts rival, Pride Fighting Championships, in a deal that will establish megafights among the outfits' titleholders and possibly attract huge pay-per-view audiences.

 Company executives declined to comment on the sales price, but a person familiar with the negotiations told The Associated Press that brothers Lorenzo and Frank Fertitta will purchase the Japan-based Pride for less than $70 million. The person was not authorized to speak to reporters and spoke on condition of anonymity.

The deal was completed Tuesday and was announced during a news conference in Tokyo, where Lorenzo Fertitta has been negotiating with Nobuyuki Sakakibara, the majority owner and chief executive of Dream Stage Entertainment Inc., Pride's owner.

"We have been talking to Pride for probably about 11 months," Lorenzo Fertitta said. "It's been a long, drawn-out process but we finally were able to put the two brands together."
