Dynamite!! USA was held on Saturday, June 2, 2007 at the Los Angeles Memorial Coliseum in Los Angeles, California. Unofficially it shattered the record for highest attendance numbers for a North American mixed martial arts event with 42,757 claimed spectators although only 3,674 paid meaning that the event was a financial disaster. Featured Brock Lenar's first MMA bout and a rematch of the classic Sakuraba Gracie fight which at the time Royce won by unanimous decision but later after being found to have highly elevated levels of testosterone (and clearly looking much larger and more muscular) the decision was overturned to a no contest.
