ONE Fight Night 14: Stamp vs. Ham is headlined by four women's World Title bouts filled with opportunities for redemption, double-champ status, and history-making moments, which makes this weekend's event that has it all.
The action goes down on September 30 at the Singapore Indoor Stadium in Kallang, Singapore, and the card is stacked from top to bottom with intriguing matchups.

But the top of the card has major repercussions for each respective division with titles on the line. With that, here are three reasons to watch ONE Fight Night 14.
1. Stamp Fairtex vs. Ham Seo Hee - ONE Interim Atomweight MMA World Title: Due to the understandable absence of ONE Atomweight MMA World Champion Angela Lee, top contenders Stamp Fairtex and Ham Seo Hee will collide for the division's interim strap in the main event.
Stamp's road back to World Title contention has been her most convincing run yet. The Thai megastar dismissed Jihin Radzuan over three rounds before stopping Alyse Anderson in a star-making performance at ONE Fight Night 10.
Her recent run of form brings her to her toughest challenge yet in Ham Seo Hee. The South Korean has been untouchable since bringing her veteran talents to the Circle. "Hamzzang" has gone 3-0 in ONE, giving her an impressive overall winning streak of nine in a row.
And with Lee expected to make an announcement on her fighting future this Saturday, the ramifications of this atomweight clash could not be any bigger in the show's exciting headliner.
2. Smilla Sundell vs. Allycia Hellen Rodrigues - ONE Strawweight Muay Thai World Title: In the co-main event, ONE Strawweight Muay Thai World Champion Smilla Sundell will return to action in a champion-versus-champion scrap. She meets fellow striking queen and ONE Atomweight Muay Thai World Champion Allycia Hellen Rodrigues.
Sundell was initially set to rematch Jackie Buntan. But when the Filipino-American withdrew due to injury, Rodrigues threw her name in the hat for the chance to double her gold. And that makes this encounter all the more intriguing.
Plus, both women have been dominant across their ONE tenures. Sundell has dispatched Diandra Martin, Milana Bjelogrlic, and Buntan en route to strawweight Muay Thai stardom. Meanwhile, Rodrigues has toppled striking royalty in Stamp and Janet Todd.
Rodrigues will hope to lace her other shoulder with a second World Title this Saturday. But if Sundell can defeat the Brazilian, she will cement her status as strawweight Muay Thai queen.
3. Danielle Kelly vs. Jessa Khan - Inaugural ONE Atomweight Submission Grappling World Title: Danielle Kelly and Jessa Khan are no strangers to one another. The two first collided two years ago. And now with the inaugural ONE Atomweight Submission Grappling World Title on the line, the contest is bigger than ever.
The grapplers met at 2021's Who's Number One? event. Khan left victorious that night, controlling Kelly to win on points. But since then, Kelly has asserted her dominance in ONE's atomweight submission grappling realm.
The American battled to an entertaining draw with Mei Yamaguchi before defeating both Mariia Molchanova and Ayaka Miura. Kelly has called her shot to become the division's queen. And now she has the chance to do so against her greatest foe.
However, Khan has the unique opportunity to defeat Kelly once again, ascend to the top of the division in her promotional debut, and make history as the first-ever ONE Atomweight Submission Grappling World Champion.
