British fighter Charlie Guest will make his ONE Championship debut on June 27, facing New Zealand’s Sam Fitzgerald in a bout streamed live on Sky Sports.
Guest, an ISKA world champion and WBC European and British kickboxing titleholder, was originally slated to fight Bampara Kouyate on ONE Fight Night 44. After Kouyate withdrew, Fitzgerald – the WBC New Zealand super‑welterweight champion – stepped in to take on the rising British star.
Standing 6 ft tall, Guest brings a highly technical and powerful stand‑up game that has earned him major titles across Europe.
On June 27 Guest will begin his quest for a ONE world title, aiming to become the next English champion to capture the coveted gold.

“This is something I’ve worked towards my entire life, and I truly believe this is only the beginning. I can’t wait to show the world exactly what I’m capable of. Dreams into reality,” Guest said.
“Massive thank you to everyone who’s supported me on this journey, my team, training partners, coaches, sponsors, friends and family. I’m beyond grateful for every bit of support along the way.
“June 27, time to show the world, I’m coming for it all. Let’s go.”

In the main event on the show, Britain’s George Jarvis will rematch Thai maestro Rungrawee Sitsongpeenong.
Jarvis knocked out Sitsongpeenong to earn a life‑changing contract and coveted roster spot with ONE Championship. Both men would later go on to challenge for the ONE world title belts, but each warrior fell short in their first attempt.
Now, nearly two years later, fate has brought these stars back together, and a victory at the historic Lumpinee Stadium could drastically change their lives once again.
For Jarvis, it’s an opportunity to beat his Thai rival once again and get a second shot at ONE world title gold.
