UFC 316: Lightweight bout late addition to Merab Dvalishvili vs. Sean O'Malley 2 card
03/06/2025 00:00
UFC 316 has a new fight.
The UFC announced Monday that MarQuel Mederos (10-1) is booked to fight newcomer Mark Choinski (8-0) in a lightweight bout on the preliminary portion of this Saturday's pay-per-view, which takes place at Prudential Center in Newark, N.J.
Eurosport was first to report the matchup.
Mederos was scheduled to fight Bolaji Oki this past Saturday at UFC Vegas 107, but withdrew due to an illness. Oki instead went on to defeat short-notice replacement Michael Aswell. The nature of Mederos' illness is not known, but he is fit to return just a week later and looks to improve to 3-0 in the UFC after scoring back-to-back decision wins over Austin Hubbard and Landon Quinones.
Choinski is undefeated in eight pro bouts, having competed most recently for Anthony Pettis FC. He submitted John Ramirez in his most recent outing and has been pulled from a scheduled APFC bout against Zach Zane on June 15 to make his UFC debut.
UFC 316 is headlined by a men's bantamweight championship rematch between Merab Dvalishvili and Sean O'Malley. Two-time women's bantamweight champion Julianna Peña defends her title against Kayla Harrison in the co-main event.
