The undefeated Polish champion reveals contractual ambiguities after four successful title defenses

Adrian Bartosiński, the undefeated KSW middleweight champion, has recently broken a telling silence by exposing controversial clauses in his contract with the Polish promotion. According to his statements, these terms include an automatic extension of his commitment after four or five fights—information he claims was withheld from him at the time of signing.
On X (formerly Twitter), the Polish fighter explained that his team had assured him his agreement was standard, similar to those of other athletes in the promotion. However, these hidden clauses, revealed after his victory over Mamed Khalidov in November 2024, have cast a shadow over his relationship with KSW.
This case reignites the debate on contractual transparency in European MMA, a recurring issue for years. Bartosiński, who has defended his title five times since April 2023, points to a system where athletes are often at a disadvantage against promoters.
When asked why he remained silent until now, the Pole cited a gradual realization, particularly after the only loss of his career. This situation echoes other similar cases in combat sports, where abusive clauses have already been called out.
KSW has yet to officially respond to these allegations, but this revelation could well reignite discussions on contractual ethics in MMA. For now, Bartosiński remains determined to defend his title, despite the uncertainties surrounding his future with the promotion.
