Two compelling MMA matchups have been added to ONE Fight Night 42 on Prime Video, which broadcasts live from Lumpinee Stadium in Bangkok, Thailand, on Friday, April 10.

The more consequential of the two pits a pair of unbeaten welterweights against each other, with the division's world title within eventual reach of whoever comes out standing.

Chase "Mannimal" Mann, a 29-year-old Arkansas native with a 7-0 record and five stoppage victories, takes on Turkish finisher Dzhabir Dzhabrailov, who at 21 years old holds an unblemished 6-0 mark with all six wins coming inside the distance.

Dzhabrailov has been even more efficient inside the ONE ring, stopping each of his three promotional opponents in under two minutes.

The winner moves into serious contention in a welterweight division currently ruled by two-sport king Christian Lee.

The second MMA bout is an all-American flyweight clash between Joshua "Flyin Hawaiian" Perreira and Gilbert Nakatani. Perreira arrives carrying unfinished business.

His promotional debut in 2025 was cut short by a knee injury suffered early against Banma Duoji, with the result eventually overturned to a no contest. Now recovered and holding a 5-0 record, the Immortal Martial Arts representative gets a second shot at making his mark on the global stage.

Nakatani, a 32-year-old California native out of Aragon Training Academy, comes in with momentum on his side. After going the distance with both reigning flyweight title-holder Yuya Wakamatsu and Jeremy Miado in back-to-back tests, he needed just two minutes to finish Eko Roni Saputra by TKO last November — his first promotional win and a result that announced him as a genuine factor in the division.
