What's at stake at ONE Fight Night 30?

An unstoppable force will meet an immovable object in the main event of ONE Fight Night 30. Ukrainian harbinger of doom Roman Kryklia will seek to defend his ONE Heavyweight Muay Thai world title for the first time against WBC Heavyweight Muay Thai kingpin Lyndon Knowles.

Meanwhile, the rivalry between Regian Eersel and Alexis Nicolas will finally be resolved in their long-awaited trilogy after splitting their first two meetings.

However, due to some drama on the scales, 'The Immortal' has been stripped of his lightweight kickboxing world title after missing weight and hydration. Only 'Barboza' will be eligible to claim 26 pounds of gold.

Elsewhere, we got a pair of debutants looking to make an immediate splash. Bantamweight Muay Thai mainstay Nico Carrillo will charter in unfamiliar waters in his first foray at featherweight against fourth-ranked Sitthichai Sitsongpeenong.

Bemedaled BJJ athlete Fabricio 'Hokage' Andrey will also look to justify the hype surrounding him against Ashley Williams in a featherweight submission grappling showdown.

Crowd-pleasers Seksan Or Kwanmuang, Sanzhar Zakirov, Thongpoon PK Saenchai, and Jihin Radzuan, among others, are all scheduled to go to war.
