5 Reasons To Watch ONE Fight Night 46 On August 14
ONE Championship returns to U.S. primetime with a loaded lineup of World Champions, undefeated MMA stars, proven contenders, and elite grapplers at ONE Fight Night 46 on Prime Video: Hemetsberger vs. Diachkova.
Broadcasting live from the iconic Lumpinee Stadium in Bangkok, Thailand, the blockbuster card features action across Muay Thai, kickboxing, MMA, and submission grappling this Friday, August 14.
At the top of the bill, two-sport queen Stella “Always Hungry” Hemetsberger puts her ONE Women’s Strawweight Muay Thai World Title on the line against Russian knockout artist Natalia “Karelian Lynx” Diachkova.
With a reigning World Champion making her first defense, another one entering a new discipline, three undefeated MMA talents looking to protect their perfect records, and a highly anticipated submission grappling rematch, there is plenty more to anticipate.
Here are five compelling reasons to watch ONE Fight Night 46.
#1 A Two-Sport Queen Defends Her Muay Thai Crown
Hemetsberger’s extraordinary rise has already taken her from the ONE Friday Fights event series to the absolute summit of two striking disciplines.
The Austrian superstar, who remains undefeated in the world’s largest martial arts organization, became her country’s first ONE World Champion by defeating Jackie Buntan for the vacant strawweight Muay Thai crown in September 2025. Five months later, she edged the Filipino-American in a highly technical kickboxing rematch to add a second belt to her collection.
Now, the 27-year-old makes her first Muay Thai World Title defense against a challenger carrying serious firepower.
Diachkova previously earned four consecutive victories in ONE before challenging for the strawweight Muay Thai belt in 2024. Although that opportunity ended in defeat, “Karelian Lynx” has steadily worked her way back into the World Title picture.
Most recently, the Russian scored a spectacular opening-round finish against Fahsai Aor Yutthachai at ONE Friday Fights 152 this past May and immediately called for a showdown with Hemetsberger.
On August 14, she gets exactly what she asked for.
#2 Muay Thai King Nico Carrillo Makes Kickboxing Debut
Nico “King of the North” Carrillo finally sits atop ONE’s featherweight Muay Thai division, but the Scottish powerhouse is wasting no time exploring new territory.
After defeating Shadow Mavinn over five grueling rounds to capture the interim crown in February, Carrillo was elevated to undisputed ONE Featherweight Muay Thai World Champion when Tawanchai PK Saenchai vacated the belt in July.
Now, the 27-year-old begins an exciting new quest.
Carrillo will make his ONE kickboxing debut against Chinese newcomer Zhou Jiaqiang, bringing the formidable power that has produced an 86 percent finishing rate across his eight promotional appearances into a different rule set.
The Scot has made it clear that his immediate focus remains on defending his Muay Thai crown, but his move into kickboxing opens up an intriguing new possibility. A victory over Zhou would show whether ONE’s newest undisputed Muay Thai king has the versatile tools to eventually chase a second belt.
#3 Undefeated MMA Stars Enter The Spotlight
Three unbeaten mixed martial artists will put their perfect professional records on the line at ONE Fight Night 46.
The most intriguing collision pits New Zealand-Vietnamese sensation Viet Anh Do against Brazilian newcomer Davi “Ajuricaba” Brandao in fast-paced flyweight action.
Both men arrive with identical 6-0 records, and neither has ever needed the judges to secure a win.
Do has finished all six of his professional opponents while building a flawless 5-0 promotional record. His latest victory, a second-round stoppage of Kyungjung Kim this past May, earned him a US$100,000 contract and a well-deserved place on ONE’s global roster.
Brandao presents an equally dangerous challenge. The 20-year-old has divided his six victories perfectly between three knockouts and three submissions, giving him the dynamic tools to end the contest wherever it goes.
Meanwhile, undefeated Polish sensation Magdalena “The Powerpuff Girl” Czaban brings a 4-0 record into her ONE debut against American star Natalie Salcedo.
The decorated former IMMAF standout has also finished every professional opponent she has faced.
With three perfect records entering the night, and Do and Brandao facing each other directly, at least one zero is guaranteed to disappear.
#4 World-Class Strikers Take Center Stage
Beyond the World Champions at the top of the card, ONE Fight Night 46 is stacked with accomplished strikers seeking to make major statements in their respective divisions.
Nontachai Jitmuangnon meets Russian standout Kiamran Nabati in a pivotal bantamweight Muay Thai contest. Nontachai enters with undeniable momentum after defeating former ONE World Title challenger Felipe “Demolition Man” Lobo, while Nabati is determined to rebound from the first professional setback of his career.
Before that loss, the Russian had built an impressive run that included victories over Suablack Tor Pran49 and former longtime divisional king Nong-O Hama.
The elite striking depth continues when former K-1 Champion and ONE World Title challenger Kana “Krusher Queen” meets Hong Kong’s Yu Yau Pui in atomweight kickboxing.
Kana owns 24 career victories and recently scored one of her biggest wins against Thai megastar Stamp Fairtex, while Yu brings a 29-4 career record into her ONE kickboxing debut after a stunning 75-second finish of “Supergirl” Anna Jaroonsak.
Russian standout Elbrus “The Samurai” Osmanov will also return to bantamweight kickboxing against Brazil’s Denis “Denizinho” Souza Jr. Osmanov has compiled a remarkable 9-1 promotional record, while Souza looks to bounce back after narrowly dropping a split decision in his ONE debut.
#5 A Decorated BJJ World Champion Is Out For Revenge
One of Brazilian Jiu-Jitsu’s brightest modern stars will make his highly anticipated ONE debut with some serious unfinished business.
Two-time IBJJF World Champion Meyram Maquine Alves faces fellow Brazilian Ruan Alvarenga in a high-level featherweight submission grappling rematch.
The 25-year-old arrives with a staggering 135-16 professional grappling record and a firm reputation as one of his generation’s most dynamic competitors.
But his promotional debut carries a deeply personal edge. Alvarenga defeated Alves outside ONE in 2025, handing the decorated grappler a bitter setback that he now fully intends to avenge on the global stage.
For Alves, August 14 represents far more than just the opportunity to introduce his world-class grappling to ONE’s audience. It is his prime chance to settle an old score.
