In a surprising move that has caught the attention of combat sports enthusiasts, European boxing champion Laura Grzyb has signed with leading Polish mixed martial arts promotion KSW, marking a significant career transition from the boxing ring to the MMA cage.
The 29-year-old Polish sensation, who holds both the EBU European and IBO International titles, brings an impressive undefeated professional boxing record of 11-0 to her new venture. Grzyb’s boxing career has been particularly noteworthy for her explosive start, securing knockouts in her first three professional outings.





While the details of her MMA debut remain under wraps, Grzyb has been actively preparing for her transition to the new sport. Her social media posts have revealed glimpses of her dedicated training sessions as she adapts her striking expertise to the multifaceted demands of mixed martial arts.

KSW, based in Warsaw, has established itself as one of Europe’s premier MMA organizations and has served as a launching pad for several high-profile athletes who later achieved international success. The promotion’s alumni include notable names such as Jan Blachowicz, Dricus Du Plessis, Mateusz Gamrot, Alexander Gustafsson, and Karolina Kowalkiewicz.
The announcement comes as KSW prepares for its next event at the Home Credit Arena in Liberec, Czech Republic. Fans can watch the upcoming show through the promotion’s official website via internet pay-per-view.
