In the main event, former ONE Heavyweight World Title challenger Mauro “The Hammer” Cerilli  executed a fantastic game plan to spoil the much-anticipated promotional debut of Abdulbasir “Dagestan Machine” Vagabov . Cerilli used the entire length of the Circle, avoiding Vagabov’s powerful right hand while looking to counter with his own haymakers. In the second round, Cerilli hurt Vagabov with a low kick, sending the Russian reeling toward the Circle Wall. Cerilli then sealed the win with a steady stream of ground strikes that forced the referee to halt the contest.
In the co-main event, flyweight standout Daichi Takenaka  submitted Ivanildo “Monstrinho” Delfino  in a high-level ground exchange between grappling specialists. Both men attempted to gain advantageous positions in a first-round stalemate. In the second frame, Takenaka took Delfino’s back and threatened with a rear-naked choke for a good two minutes as the Brazilian just barely made it to the bell. In the final stanza, Takenaka took the back again early, this time successfully snaking his forearm underneath Delfino’s chin to complete the choke and force the tap.
“Pretty Boy” Kwon Won Il  overcame a game effort from “The Ghost” Chen Rui , winning by knockout in the third round. The two power punchers traded thunderous strikes at the center of the Circle for most of the contest, with neither man willing to back down. A thrilling second round left both men on the brink of exhaustion. Chen, in particular, took Kwon’s best shots but was still standing after 10 minutes of action. In the opening moments of the final frame, Kwon cornered Chen with another combination, this time delivering a crushing blow to the ribs that ended matters abruptly.
WMC Muay Thai World Champion Beybulat Isaev  made quick work of Serbian Kickboxing Champion Mihajlo Kecojevic , knocking the taller fighter out with a single punch in the first round and setting a new record for the fastest ONE Super Series KO at light heavyweight. Kecojevic used his size and reach advantage early on, pressuring Isaev against the Circle Wall. Answering back, Isaev stood his ground and unleashed a sharp counter right hand that sent Kecojevic crashing face-first into the canvas. The referee immediately called off the contest.
