Naoya Ogawa
In April 2004, Silva took part in the Heavyweight Grand Prix tournament, whose first round saw him facing sumo wrestler Henry "Sentoryu" Miller, only 85lbs lighter. Sentoryu accomplished a takedown on Silva and attacked his guard, only for Silva's height to neutralize his ground and pound attempts, as the sumo did not reach to his head. Miller finally got side control, but then Silva reversed him with a Kimura lock and made him tap out. The pro wrestler then advanced to the second round, being pitted against former world judo champion Naoya Ogawa, who won the fight by takedown and ground and pound TKO.
