Which ONE Fight Night 46 Fights Should Fans Watch?
The obvious starting point is the championship main event.
Hemetsberger vs. Diachkova puts an established world champion against a dangerous challenger with the experience and power to make the fight uncomfortable.
But Carrillo vs. Zhou may be just as interesting for striking fans.
Carrillo has become one of ONE’s most recognizable Muay Thai fighters, and seeing how his style translates to kickboxing gives the matchup an extra layer.
Nontachai vs. Nabati should also provide plenty of action, while the ONE debut of Meyram Maquine Alves gives grappling fans something completely different.
There is also MMA throughout the card, including Jhanlo Mark Sangiao’s return against Marcos Aurelio.
