Over the course of his professional career, which began in 2010, Sulecki has built a record that includes a challenge for the WBO middleweight title and victories over several respected international opponents.
Standing 1.85 m (6 ft 1 in) tall with a reach of 173 cm, Sulecki combines size and technical skill to compete at the highest levels of the sport. His career has been marked by a steady climb through regional and national titles before stepping onto the world stage. He remains an active figure in the professional boxing scene, representing Poland in major international bouts.
Early Life and Background
Maciej Sulecki was born on 2 May 1989 in Warsaw, Poland, where he grew up and was first introduced to the sport of boxing. The Polish capital has a long tradition of producing competitive fighters, and Sulecki developed his early interest in the ring during his formative years in the city. His physical attributes, including his tall frame, would later become central to his style as a professional.
As a young athlete, Sulecki channeled his energy into amateur boxing, where he quickly established himself as a decorated talent. He compiled an amateur record of 110 wins against 30 losses, a foundation that reflected both his experience and his dedication to the craft. During this period, he became a three-time Polish Junior champion, an achievement that signaled his potential to progress into the professional ranks.
Path to Boxing
Sulecki’s transition from amateur to professional boxing came in June 2010, when he made his professional debut in Kielce, Poland. In that first fight, he defeated Adam Gawlik by knockout in the opening round, immediately announcing his arrival as a professional. The victory gave him the momentum and confidence needed to step into a demanding schedule of bouts across Poland.
By June 2012, Sulecki had begun to face seasoned opposition, defeating former welterweight world champion Yuriy Nuzhnenko by unanimous decision. The win against a well-known veteran demonstrated that Sulecki could handle experienced opponents over longer rounds. From there, he pieced together fifteen consecutive victories, steadily building the résumé that would eventually earn him a shot at national titles and bigger stages.
Maciej Sulecki Career
Early Career (2010–2014)
Maciej Sulecki’s early professional years were defined by consistent wins across Poland and a growing reputation for finishing fights. In November 2013, he fought Lukasz Wawrzyczek for the vacant Republic of Poland middleweight title and won by unanimous decision, claiming his first major professional belt. The following May, he added the Polish International super-middleweight title by defeating Nicolas Dion of France over ten rounds.
Later in 2014, Sulecki faced former European champion and WBA middleweight world title challenger Grzegorz Proksa at the Krakow Arena in Poland. In a high-profile all-Polish showdown, Sulecki stopped Proksa in the seventh round, finishing the fight with a right-hand counterpunch after weathering an awkward opening phase. The victory established Sulecki as one of the leading middleweights in his home country.
International Breakthrough (2015–2017)
Following his victory over Proksa, Sulecki partnered with promoter Lou DiBella and manager Al Haymon, opening the door to opportunities in the United States. He made his U.S. debut in April 2015 at the UIC Pavilion in Chicago, stopping Darryl Cunningham in the third round. He followed that with a first-round stoppage of Jose Miguel Berrio at the Prudential Center, performances that pushed him onto Sherdog’s Top 10 middleweights list.
In 2016, Sulecki scored one of his most notable wins by stopping previously unbeaten Hugo Centeno Jr. in the final round of a ten-round bout, marking his fifth consecutive knockout. After moving down to light-middleweight in 2017, he defeated Jack Culcay by unanimous decision in October of that year, on the undercard of the World Boxing Super Series quarter-final between Krzysztof Wlodarczyk and Murat Gassiev. The run cemented his status as a credible contender on the international circuit.
World-Title Contender Era (2018–2019)
Sulecki’s growing profile led him to a high-profile showdown with former world middleweight champion Daniel Jacobs, who entered the bout ranked near the top of the middleweight division by all four major sanctioning bodies. Although Sulecki lost the fight by unanimous decision, the opportunity placed him firmly in the mix at world level. The experience of facing an elite opponent added valuable seasoning to his career.
He rebounded with a victory over Puerto Rican veteran Gabriel Rosado in a hard-fought grudge match, a win that moved him up to a number-two ranking by the WBO. That ranking made him the mandatory challenger for the WBO middleweight title, setting up a fight against Demetrius Andrade. In the 2019 world-title bout, Andrade proved too strong, taking every round and dropping Sulecki to the canvas in the process.
Super-Middleweight Move (2024)
In August 2024, Sulecki faced Diego Pacheco in Carson, California, with both the WBC USA and WBO International super-middleweight titles on the line. The bout marked his continued activity in the super-middleweight division and his willingness to test himself against rising contenders. Sulecki was ultimately stopped in the sixth round after a left body hook sent him to the canvas, ending his bid for the two belts.
Style and Strengths
Maciej Sulecki fights from an orthodox stance, using his 1.85 m frame and 173 cm reach to control distance against most middleweights and super-middleweights. His style has been built around steady pressure, accurate counterpunching, and the ability to wear opponents down over the course of longer fights. While he has shown finishing power, particularly during a stretch of consecutive knockouts between 2015 and 2016, many of his wins have come by decision, reflecting a patient and calculated approach.
Notable Events and Milestones
Among the defining moments of Sulecki’s career are his seventh-round stoppage of Grzegorz Proksa in 2014 and his U.S. debut knockout of Darryl Cunningham in 2015. His unanimous decision over Jack Culcay in 2017 and his victory over Gabriel Rosado stand out as significant wins that pushed him toward world-title contention. The 2019 challenge to Demetrius Andrade for the WBO middleweight title remains the headline milestone of his professional career so far.

The breakdown reflects a fighter who balances consistent output with the ability to finish when openings appear.
Regional and National Highlights
Sulecki’s first major title came in November 2013, when he outpointed Lukasz Wawrzyczek for the vacant Republic of Poland middleweight title. He added the Polish International super-middleweight title in May 2014 by beating Nicolas Dion of France over ten rounds. These early belts established him as a leading figure in Polish boxing and laid the groundwork for his later international opportunities.
International and U.S. Performances
On the international stage, Sulecki has recorded wins over Yuriy Nuzhnenko, Darryl Cunningham, Jack Culcay, Hugo Centeno Jr., and Gabriel Rosado, among others. His victories over the unbeaten Centeno Jr. and the experienced Rosado were particularly important in elevating his world rankings. These results ultimately positioned him as a credible top-tier contender during the late 2010s.
