Z-Fight Night 4 will take place on Saturday, May 9, 2026. You can catch all the live MMA action exclusively on UFC Fight Pass! A developing promotion presents a competitive card featuring hungry fighters looking to make an impact.
Z-Fight Night, usually shortened to ZFN, is a South Korean MMA promotion created by Jung Chan-sung, better known as “The Korean Zombie.” Public reporting says it held its first event in Seoul in June 2024, and its own materials identify ZFN as the organization name. ZFN is important because it reflects a renewed effort to build a stronger Korean domestic MMA stage with a recognizable founder at the center. The promotion’s niche is not style-based but regional: it is a Korean platform built to serve and elevate Korean MMA.
