South Africa’s own Willie “White Lion” van Rooyen will make his ONE Championship debut on Saturday, 8 November 2025, live from Lumpinee Stadium, Bangkok, at 4:00 AM (South African time).

The 23-year-old undefeated flyweight (7–0) enters the global stage against Uzbekistan’s Avazbek “Ninzya” Kholmirzaev, known for his explosive knockouts and 92% finishing rate.

A Proud Moment for Legal Clinch Management

Legal Clinch Management is immensely proud to stand behind Willie as he takes this monumental step in his career. Representing South Africa on the world stage, the “White Lion” showcases the heart, discipline, and talent that define African combat sports.

“We’re honoured to guide Willie on this journey,” said Legal Clinch Management. “His drive, humility, and world-class ability reflect exactly what Legal Clinch stands for — excellence and integrity in athlete representation.”

The Road to ONE

After capturing the EFC Flyweight Title in just 37 seconds and defending it with a clinical rear-naked choke, van Rooyen now steps into the world’s biggest martial arts organization ready to make a statement. Trained by Coach Nico Mothata (A-Team Stars) , Willie brings elite striking and submission prowess to ONE’s global spotlight.
