In the main event, home favourite Kevin "The Silencer" Belingon (17-5), who is currently riding a four-bout winning streak, will take on former bantamweight world title challenger Andrew Leone (8-3) in a contest with huge title implications.
Both are seeking a rematch against reigning ONE Bantamweight World Champion Bibiano "The Flash" Fernandes, and will have to go through each other to secure it.
"I know Andrew Leone is a tough opponent, and I need to be at my best to win," said Belingon during a press conference on Tuesday.
"It’s going to be one of my biggest matches to date and I am very thankful to ONE Championship for allowing me to be a part of this historic event.
"I can’t leave anything to chance. I have to give another great performance."
Leone also knows what’s at stake in this matchup, hence he isn’t taking his Filipino counterpart lightly.
"This is a tremendous opportunity for me and I can’t wait to go up there and show what I can do, to perform to the best of my ability," said Leone.
"Kevin Belingon is a tough guy. He’s a hard puncher and he has power. But I’m not worried about his striking. I’ve faced tough guys before. All I can say is that I’ll be ready."
