K1 Dynamite!! USA(2007)

K1 Dynamite!! USA is a mixed martial arts event held on June 2, 2007, at the Los Angeles Memorial Coliseum. The card drew a claimed 42,757 spectators, setting an unofficial North American MMA attendance record, though only 3,674 paid tickets were sold, making it a financial failure. The event featured Brock Lesnar's MMA debut and a rematch between Sakuraba and Royce Gracie, whose original bout Royce won by unanimous decision. That victory was later overturned to a no contest after Royce tested positive for elevated testosterone levels.
