"I'm feeling great and I'm really happy to be here. I'm feeling good about the fight, like how I felt with all my previous fights. I think this is going to be the biggest event in my life and my sporting [career]," said Natalia Diachkova.
'Karelian Lynx' has a stellar 30-4 professional record and a perfect 4-0 in ONE Championship.
After stomping the competition on the ONE Friday Fights circuit, which saw her claim three knockout wins, Diachkova earned the right to challenge Sundell for the ONE women's strawweight Muay Thai world title this Friday.
Diachkova scored two straight first-round knockout wins against Dokmaipa Fairtex and Lena Nocker in her first two fights under the ONE Championship umbrella before she settled for a unanimous decision win over Hannah Brady last September.
She resumed her knockout count in her last match when she stopped Chellina Chirino in the opening round of their fight this past March.
ONE Fight Night 22 is available live and free to all Prime Video subscribers in the United States and Canada.
