Two fighters with unfinished business headline a pair of MMA matchups added to ONE Fight Night 43: Tang vs. Gasanov on Friday, May 15, live in U.S. primetime from Lumpinee Stadium in Bangkok.

Alibeg Rasulov returns to the lightweight division to face Lucas Gabriel in a bout that means something different to each man.

Rasulov announced himself in ONE with a dominant win over former champion Ok Rae Yoon, which earned him a shot at Christian Lee's lightweight title in 2024.

An accidental eye poke produced a no-contest that night, and the 2025 rematch ended in a TKO loss — the first defeat of his professional career.

The 33-year-old carries a 14-1 record and championship-level experience, but the immediate task is simpler than a title shot: get back to winning.

Gabriel makes that task harder than it might look on paper. The 26-year-old Brazilian has won four straight in ONE, most recently stopping Magomed Akaev in February, and his 11-1 record includes an unblemished promotional run.

A win over a former title challenger would push Gabriel directly into the lightweight conversation. Rasulov cannot afford to take him lightly, and Gabriel has every reason to push the pace.

The second addition takes the card to strawweight, where former ONE Strawweight MMA World Champion Yosuke Saruta meets Fabio Henrique.

Saruta's history in the division is genuine. The Tokyo native dethroned Joshua Pacio to claim the title in January 2019. It was a result that announced him as one of the best strawweights on the planet.

He dropped the belt to Pacio in the first defence and has since fallen in three consecutive decisions, most recently to Keito Yamakita at ONE Fight Night 24.

At 38, the window is narrowing, and Saruta arrives in Bangkok knowing a fourth straight loss would seriously damage his standing in the division.

Henrique enters looking for a response of his own after dropping his promotional debut to Lee Seung Cheol at ONE Fight Night 41 in March.

The Brazilian carries raw finishing power and the kind of motivation that comes with needing to prove that first result was not the full picture.
