UFC Fight Night: Fiziev vs. Torres
27 Jun 2026

Oleksiejczuk's Baku run ended abruptly when Magomedov found a first-round guillotine choke and forced the tap at 3:25. The result was another reminder that Oleksiejczuk can make fights violent quickly, but he remains vulnerable when a strong middleweight turns the scramble into a submission exchange.

Key moments

  • The fight ended in the opening round before Oleksiejczuk could drag it into a longer striking battle.
  • Magomedov secured the guillotine choke at 3:25 of round one.
  • Oleksiejczuk's recent three-fight winning run stopped in Baku.
  • The loss pushed his UFC middleweight record back toward the volatility that has defined most of his run.

Opponent: Marc-André BarriaultunanimousR3 5:00
UFC Fight Night: Bautista vs. Oliveira
7 Feb 2026

Oleksiejczuk and Barriault turned their February meeting into the kind of slugfest both men usually promise, and Oleksiejczuk did enough over three rounds to secure the unanimous decision. The win mattered because it showed he could still bank a hard fight on the scorecards instead of needing a first-round finish to control the outcome.

Key moments

  • The fight lasted the full fifteen minutes in a matchup built around pressure and exchanges.
  • Oleksiejczuk won the decision cleanly after a competitive stand-up battle.
  • The bout earned Fight of the Night honors.
  • It gave him a third straight win after the rough 2024 slide.

Opponent: Gerald MeerschaertpunchesR1 3:03
UFC 319
16 Aug 2025

Oleksiejczuk overwhelmed Meerschaert with a first-round barrage, proving his left hand was still plenty when he can force opponents to trade with him instead of tie him up. The finish added another fast UFC stoppage to a profile already defined by early damage.

Key moments

  • Oleksiejczuk never allowed Meerschaert to settle into a grappling-based approach.
  • The left hand remained the fight-changing weapon throughout the opening round.
  • He closed the show by TKO at 3:03 of round one.
  • The win made it back-to-back stoppages after the Dumas finish.

UFC 314
12 Apr 2025

  • Dumas never got a calm range-finding round to work with.
  • Oleksiejczuk finished with punches and elbows at 2:49 of round one.

3 Aug 2024

Oleksiejczuk pushed Magomedov in a short-notice Abu Dhabi co-main event, but he still came out on the wrong side of a unanimous decision after fifteen hard minutes.

UFC 302
1 Jun 2024

UFC Fight Night: Holloway vs. The Korean Zombie
26 Aug 2023

  • Oleksiejczuk fired back instead of retreating and dragged the fight into a slugfest.

UFC Fight Night: Cannonier vs. Strickland

6 Aug 2022

UFC 272
5 Mar 2022

Oleksiejczuk had a strong opening round built on pressure and body punching, but Jacoby settled in and won the last ten minutes with cleaner damage and better control. By the end it was one of those fights where Oleksiejczuk's fast start was not enough once the opponent adjusted.

  • Oleksiejczuk did some of his best work in round one by forcing Jacoby backward.
  • Jacoby badly hurt him in round two with a heavy punching-and-knee sequence.

UFC 267
30 Oct 2021

UFC 260
27 Mar 2021

Bukauskas did a lot of the cleaner outside work early, but Oleksiejczuk kept chasing and made the final round ugly enough to steal the fight on the cards. His body attack mattered most late, especially once Bukauskas started to slow under the pressure.

Key moments

  • Both men had moments landing cleanly in the first round.
  • Oleksiejczuk's left hand and body work improved as the fight wore on.

23 Feb 2020

Oleksiejczuk originally left the cage with a unanimous decision win after weathering Rountree's early offense and doing some of his best work late, especially with third-round top control.

  • Wikipedia lists it as his middleweight debut despite a missed weight.

The Read

Style, strengths, and where this fighter stands.

Oleksiejczuk is one of the division's purest chaos merchants: a fast-starting middleweight with heavy hands, relentless pressure, and very little interest in long-range safety. UFC.com lists him at 5.73 significant strikes landed per minute with 53% accuracy, and the profile backs up what the tape usually shows: if he gets the kind of firefight he wants early, he can bury opponents before they settle.

That volatility cuts both ways, which is why his run still swings so hard fight to fight. Oleksiejczuk lost to Michel Pereira, Kevin Holland, and Sharabutdin Magomedov in 2024, then rebuilt with stoppages over Sedriques Dumas and Gerald Meerschaert plus a Fight of the Night decision against Marc-Andre Barriault before Abusupiyan Magomedov caught him in Baku. He remains dangerous because even the losses rarely erase how much damage he can create in the opening minutes.
