UFC makes emergency addition to this weekend’s event

UFC Vegas 107 replaces MarQuel Mederos with Michael Aswell against Bolaji Oki

MarQuel Mederos is out of his fight with Bolaji Oki on the UFC Vegas 107 prelims. Former Dana White Contender Series cast-off Michael Aswell will replace him.

Oki was a hyped prospect from DWCS 2023, but lost his second UFC appearance in a jump in competition against Chris Duncan. Aswell lost his fight on 2024's DWCS, but has since picked up a win on the regional scene.

Aswell was scheduled to fight in Fury FC on June 22, so he should be midway through fight camp ahead of his appearance in the UFC APEX this weekend.

With this replacement fight, UFC Vegas 107 keeps eleven fights.
