Ludovit Klein

Klein closed 2025 with one of the best wins on his UFC ledger, edging Mateusz Rębecki over three rounds at UFC 321. The result mattered because it came directly after the Gamrot main-event loss and returned him to the lightweight climb with a Fight of the Night performance rather than a quiet rebound.

Key moments

• Beat Rębecki by majority decision after fifteen minutes.
• Earned Fight of the Night honors for the performance.
• The win followed Klein's first 2025 result, a loss to Mateusz Gamrot.

Gamrot handed Klein a main-event loss over five rounds' worth of spotlight compressed into fifteen minutes. The fight is important context because it halted the long lightweight upswing and tested whether Klein's newer decision-based style could hold against a higher-ranked grinder.

Key moments

• Lost a unanimous decision to Gamrot after three rounds.
• The defeat snapped Klein's streak of four straight UFC wins.
• He answered it later in the year with the majority decision over Mateusz Rębecki.

Klein beat Roosevelt Roberts over three rounds and kept the lightweight rebuild moving in Paris. The result did not come by finish, but it reinforced the bigger trend on the profile: he had become a far more reliable minute-winner at 155 than the earlier feast-or-famine featherweight version.

Key moments

• Won a unanimous decision over Roberts in Paris.
• The fight followed the Thiago Moisés decision win from June 2024.
• It pushed Klein's UFC winning streak to five before the Gamrot loss.

Moisés gave Klein another legitimate lightweight measuring stick, and Klein handled the test over a full three rounds. That win mattered because it stacked a known UFC grappler onto the same lightweight run that had already included Devonte Smith, Mason Jones and Ignacio Bahamondes.

Key moments

• Beat Moisés by unanimous decision in Louisville.
• The bout extended Klein's UFC winning streak to four at the time.
• It came three months after the AJ Cunningham stoppage.

Klein's only recent stoppage win came when he folded AJ Cunningham with a front kick to the body and follow-up punches late in round one. The finish was useful evidence that the cleaner decision-heavy version still carries the same old burst once the opening is there.

Key moments

• Stopped Cunningham at 4:36 of the opening round.
• The body-kick finish gave Klein his third straight UFC win.
• It set up the later 2024 decision wins over Thiago Moisés and Roosevelt Roberts.

Klein's win over Bahamondes was one of the clearest signs that his lightweight rebuild was real. He handled a dangerous long-range striker over three rounds, and the result mattered because it followed the Jai Herbert draw and gave him another credible UFC name on the decision-heavy run.

Key moments

• Beat Bahamondes by unanimous decision after fifteen minutes.
• The win came directly after Klein's majority draw with Jai Herbert in March 2023.
• It set up the later 2024 stoppage of AJ Cunningham.

Herbert and Klein fought to a majority draw in London, a result that neither fully reset nor really damaged Klein's momentum at lightweight. It mattered because it kept the run alive between the Mason Jones and Ignacio Bahamondes wins without giving him the clean result he wanted.

Key moments

• Officially fought Herbert to a majority draw over three rounds.
• The bout followed Klein's July 2022 win over Mason Jones.
• He returned that August and beat Ignacio Bahamondes by unanimous decision.

Jones gave Klein another sturdy lightweight test, and Klein answered by winning all three rounds on the scorecards. The result mattered because it followed the close Devonte Smith split decision and showed that the move to 155 was producing repeatable UFC success rather than a one-off correction.

Key moments

• Beat Jones by unanimous decision after fifteen minutes in London.
• The win was Klein's second straight UFC victory at lightweight.
• It set up the March 2023 meeting with Jai Herbert.

Klein edged Devonte Smith by split decision in a fight he needed after the rough 2021 run. The result mattered because it was his first UFC lightweight win and the real start of the streak that rebuilt his position inside the promotion.

Key moments

• Won a split decision over Smith after three rounds.
• The bout followed back-to-back UFC losses to Michael Trizano and Nate Landwehr.
• It became the first step in the later run that included Mason Jones and Ignacio Bahamondes.

Landwehr dragged Klein into a wild fight and eventually submitted him with an anaconda choke in the third round. The loss mattered because it left Klein 0-2 across his last two UFC appearances at that stage and forced the eventual reset that worked better once he committed to lightweight.

Key moments

• Lost to Landwehr by anaconda choke at 2:22 of round three.
• The defeat followed the May 2021 decision loss to Michael Trizano.
• Klein answered the slump by beating Devonte Smith in his next fight.

Trizano outpointed Klein over three rounds and gave the Slovakian his first UFC loss on the scorecards. The result mattered because it took some shine off the electric Shane Young debut finish and began the two-fight slide Klein had to solve by changing divisions.

Key moments

• Dropped a unanimous decision to Trizano after fifteen minutes.
• The loss came directly after Klein's UFC debut knockout of Shane Young.
• It preceded the October 2021 submission loss to Nate Landwehr.

Klein's UFC debut became an instant highlight when he replaced Nate Landwehr, missed the featherweight limit, and still knocked out Shane Young in the first round at UFC 253. The head-kick-and-punches finish announced the regional finisher to the UFC audience in the most direct way possible.

Key moments

• Made his UFC debut as a short-notice replacement for Nate Landwehr.
• Finished Young by head kick and punches at 1:16 of round one.
• The bout proceeded at a 150-pound catchweight after Klein missed the featherweight limit.

Klein tuned up for the UFC call by stopping Łukasz Sajewski in the first round at Oktagon Prime 3. The result mattered because it gave him a final regional win after the João Paulo Rodrigues and Willian Lima finishes and sent him into the UFC on a clean run of momentum.

Key moments

• Stopped Sajewski by first-round TKO at 3:49.
• The bout was Klein's last fight before his September 2020 UFC debut.
• It extended his winning streak to five at the time.

Rodrigues made Klein work into the third round, but Klein still found the head kick that ended the fight almost immediately after the stanza began. The result mattered because it showed he could carry the finishing threat late, not only in first-round bursts.

Key moments

• Knocked out Rodrigues with a head kick at 0:46 of round three.
• The finish followed Klein's June 2019 stoppage of Willian Lima.
• It helped set up the later UFC opportunity after another regional win over Łukasz Sajewski.

Lima was another quick regional victim as Klein continued to pile up stoppages on the Oktagon circuit. The result mattered because it turned the decision over Arbi Mezhidov into a fresh run of finishes leading toward the UFC contract.

Key moments

• Stopped Lima with punches at 2:27 of the opening round.
• The finish came seven months after the Arbi Mezhidov decision win.
• It preceded the third-round head-kick knockout of João Paulo Rodrigues.

Mezhidov forced Klein into a full three-round fight, and Klein responded with a clean unanimous decision. The bout mattered because it broke up the string of regional finishes and showed he could still bank rounds when the knockout did not arrive.

Key moments

• Beat Mezhidov by unanimous decision after fifteen minutes.
• The result followed Klein's stoppage wins over Kamil Selwa and Matěj Kuzník in 2018.
• It became the bridge to his 2019 Oktagon knockout run.

Selwa survived the opening frame, but Klein still closed the fight in the second round with punches. The result mattered because it preserved his rebound after the Aiden Lee loss and kept 2018 moving in the right direction on the regional scene.

Key moments

• Stopped Selwa by second-round TKO, though Sherdog does not list the exact time.
• The win followed the March 2018 doctor stoppage against Matěj Kuzník.
• It came before Klein's decision win over Arbi Mezhidov.

Kuzník pushed Klein deeper than most opponents, but Klein still won when the doctor halted the fight after four rounds. The result mattered because it showed Klein could win an attritional fight after the rough closing stretch of 2017.

Key moments

• Defeated Kuzník by doctor stoppage at the end of round four.
• The bout followed the November 2017 head-kick knockout of Krzysztof Klaczek.
• It helped Klein rebuild after the submission loss to Aiden Lee.

Klein needed only two minutes to head-kick Klaczek out at Oktagon 4. The finish mattered because it helped stabilize things immediately after the Aiden Lee submission loss and reminded everyone how dangerous his kicking game remained.

Key moments

• Knocked out Klaczek with a head kick at 2:00 of round one.
• The bout came one month after Klein lost to Aiden Lee in Cage Warriors.
• It preceded the longer four-round win over Matěj Kuzník.

Aiden Lee handed Klein a first-round submission loss in Cage Warriors, one of the more important setbacks on the regional record. It mattered because it interrupted the 2017 rise and forced Klein to show he could rebound rather than simply overwhelm lesser opposition.

Key moments

• Lost by rear-naked choke at 2:34 of round one.
• The defeat followed three straight regional wins in 2017.
• Klein rebounded one month later by head-kicking Krzysztof Klaczek.

Besztercei nearly made it out of the opening round before Klein still found the rear-naked choke finish. The result mattered because it kept a busy 2017 moving after the ACB wins over Ahmed Abdulkadirov and Khusein Maltsagov.

Key moments

• Submitted Besztercei with a rear-naked choke at 4:56 of round one.
• The finish came six weeks after Klein's guillotine win over Ahmed Abdulkadirov.
• It was Klein's final victory before the Aiden Lee loss.

Klein proved he was more than a kick-heavy striker by guillotining Abdulkadirov early in the second round at ACB 60. The result mattered because it gave him a quality road win shortly after the Khusein Maltsagov knockout.

Key moments

• Submitted Abdulkadirov with a guillotine choke at 0:44 of round two.
• The win followed Klein's knee knockout of Khusein Maltsagov in April 2017.
• It set up the June 2017 rear-naked choke finish of Moric Besztercei.

Maltsagov carried Klein into round two, but Klein still found the knockout knee that ended matters in Minsk. The result mattered because it was the first bounce-back win after the Igor Tarytsa loss and immediately restored momentum.

Key moments

• Knocked out Maltsagov with a knee at 3:29 of round two.
• The finish came five weeks after Klein's loss to Igor Tarytsa.
• It started a three-fight winning streak before the Aiden Lee setback.

Tarytsa caught Klein with a punch late in the opening round and handed him the only knockout loss on the professional record. The result mattered because it was a sharp interruption in an otherwise aggressive early-career rise.

Key moments

• Lost by punch knockout at 4:58 of round one.
• The defeat followed Klein's 2016 submission wins over Aleksandar Janković and Michal Stefek.
• He answered the setback in April 2017 by knocking out Khusein Maltsagov.

Klein stayed on the mat long enough to armbar Janković in the opening round, adding another early submission to the ledger. The result mattered because it continued the 2016 stretch that showcased the grappling side of a fighter better known later for highlight strikes.

Key moments

• Submitted Janković with an armbar in round one.
• Sherdog lists the method and round but no exact stoppage time for the finish.
• The win followed Klein's forty-second guillotine over Michal Stefek.

Stefek lasted only forty seconds before Klein wrapped up a guillotine choke. The result mattered because it reinforced how quickly Klein could finish even before the later UFC years made him look more decision-oriented.

Key moments

• Submitted Stefek by guillotine choke at 0:40 of round one.
• The bout came six months after Klein's armbar finish of Samuel Ribansky.
• It set up the following month's armbar win over Aleksandar Janković.

Ribansky pushed Klein into a second round before Klein closed with an armbar right at the horn. The result mattered because it kept the early unbeaten run intact and showed another way Klein could end a fight besides strikes.

Key moments

• Submitted Ribansky with an armbar at the start of round two.
• The win followed the July 2015 guillotine over Adam Németh.
• It preceded the March 2016 quick submission of Michal Stefek.

Németh was dispatched in a minute by guillotine as Klein kept stacking fast regional finishes in 2015. The result mattered because it followed the triangle choke over Kamil Tarnawski and confirmed that the young Klein was not relying on one single finishing route.

Key moments

• Submitted Németh by guillotine choke at exactly 1:00 of round one.
• The finish came seven weeks after Klein beat Kamil Tarnawski.
• It moved him to 4-0 as a professional.

Tarnawski survived the opening frame, but Klein eventually locked up a triangle choke in round two. The result mattered because it showed the early pro version of Klein was just as comfortable finishing on the mat as he was later with kicks and punches.

Key moments

• Submitted Tarnawski with a triangle choke at 1:35 of round two.
• The bout followed Klein's pro debut win over Martin Mihálik in December 2014.
• It set up the later first-round guillotine of Adam Németh.

Klein's professional debut lasted only twenty-seven seconds before he found a rear-naked choke on Martin Mihálik. The bout mattered because it established from the start that his record was going to be built on fast finishes.

Key moments

• Won his pro debut by rear-naked choke at 0:27 of the first round.
• The finish launched the unbeaten start to Klein's professional career.
• It was the first of several early submission wins before his UFC move.
