The action moves across the pond for Ultimate Fighting Championship 75, a multifight contest filmed live inside the O2 -- a mammoth London entertainment district that includes a 23,000-seat arena. Highlights include a brawl between UFC light heavyweight champion Quinton "Rampage" Jackson and Pride Fighting champ Dan Henderson, plus a heavyweight bout between Pride veteran Mirko "Cro Cop" Filipovic and French muay Thai kickboxer Cheick Kongo.
