Aoki (20-4), who was originally rumored to be rematching lightweight champion Joachim Hansen on the card, had won three-straight bouts before moving up to welterweight to take on Hayato Sakurai, suffering a TKO loss in just 27-seconds at DREAM 8 in April. An accomplished grappler, Ribeiro (20-2) returned to action in April following a September 2007 loss to Gesias Calvancante, defeating Katsuhiko Nagata via first-round TKO at DREAM 8.
Filho (16-1), a former WEC middleweight champion, checked into rehab for substance abuse following his controversial title defense over Chael Sonnen in late-2007. After missing weight for their rematch, Filho looked unimpressive in suffering a unanimous decision loss to Sonnen in a non-title bout last November. A kickboxer, Mahoef has won six of his last seven bouts, earning all six victories by first-round (T)KO.
DREAM also added a lightweight bout between Katsunori Kikuno and Andre Amade to the July 20th card.
