Tournament favorite Hatsu Hioki, who is currently riding a 4-fight win streak, made his way to the semi-finals by notching a couple of submission wins over Ronnie Mann and Chris Manuel in previous rounds of the tournament.

Masanori Kanehara earned his spot among the three other tournament participants with a pair of unanimous decision wins over Chan Sung Jung and Jong Man Kim.

Sengoku lightweight champion Satoru Kitaoka (24-8-9) is scheduled to appear on the fight card as well. He's the only non-tournament fighter at the moment to be officially announced for the event.
