“I’m ready for war” - Tongan warrior Isi Fitikefu ready to lay it all on the line against Japanese standout Hiroyuki Tetsuka in Denver

Isi Fitikefu is determined to do what it takes to get that all-important mark in his win column.

The Tongan star will face the streaking Hiroyuki Tetsuka in a pivotal welterweight MMA match at ONE 168: Denver on September 6 at Ball Arena in ONE Championship's first live United States card this year.

In an interview with the promotion, Fitikefu said he's ready to lay it all on the line when he faces the versatile finisher Tetsuka in Denver.

Isi Fitikefu said:

"I want to put on a good fight, and if it becomes a war, I’m ready for war. I’m ready to die in there if I have to. I’m not looking ahead. I’m not leaving it in there – all or nothing.”

Fitikefu, a former rugby player, was a perfect 7-0 when he entered ONE Championship at ONE on Prime Video 4 against Ruslan Emilbek Uulu in Singapore.

Despite a stinging split decision defeat to Emilbek Uulu, Fitikefu never lost composure and proceeded to score a first-round submission win over Brazil's Valmir Da Silva in his next match at ONE Fight Night 9.

Determined to build momentum to a potential world title shot, Fitikefu must face the in-form Tetsuka.

The Japanese standout is 6-1 in ONE Championship and rides an impressive five-fight winning streak.
