Brave CF Champ Borislav Nikolic Takes Short-Notice UFC Belgrade Debut

UFC Belgrade just got a late shuffle at bantamweight. Josias Musasa is off his scheduled bout with Mark Vologdin this weekend, and Brave CF champion Borislav Nikolic has agreed to step in on short notice — in his own backyard. Nikolic fights out of Belgrade, so he'll make his UFC debut in front of a home crowd.

That's a serious replacement to draw on short notice. Nikolic carries a 16-2 record and a six-fight winning streak, having claimed the Brave CF bantamweight title last June before defending it at Brave CF 100 in November. He's been one of the more active champions on the regional scene, and now he gets thrown straight into the deep end against a fighter with UFC-level tools.

Vologdin's Unusual Path

Vologdin (12-4-2) is a curious case. He's one of the few Contender Series fighters who actually lost his audition but earned a contract anyway — Dana White liked what he saw enough to hand him a deal, plus a bonus, after his 2025 Fight of the Year contender against Adrian Luna Martinetti. Martinetti, for context, sits at 17-2 in his own right, so that was no soft matchup to build a reputation on.

Vologdin's actual promotional debut came in April at UFC Winnipeg, where he fought John Castaneda to a third-round draw. Castaneda is a grizzled 21-8-1 veteran with six submissions to his name, so holding him even was a respectable line on the resume for a newcomer. Vologdin still hasn't officially won inside the Octagon, but he hasn't lost either.

Styles and Stakes

Style-wise, this is a fun clash of two guys who like to make things happen. Both come in with more grappling than their striking-first reputations suggest, and Nikolic's streak has been built on consistency rather than a single highlight-reel finish. Short-notice replacements are always a gamble, but a reigning champion cutting the line to debut at home is about as motivated as a fill-in gets.

The card is topped by a welterweight scrap between Uros Medic and Daniel Rodriguez. Rodriguez (20-5) is the #15-ranked welterweight and rolls in off a unanimous-decision win over Kevin Holland, giving the main event some ranked weight to anchor the night.

For Nikolic, the math is simple. Beat Vologdin in Belgrade and he arrives in the UFC with a statement win, a hometown story, and a streak that now stretches to seven. Lose, and he learns the hard way that stepping up on days' notice against a hardened prospect is a different animal entirely.
