Polish combat sports athletes are preparing for various upcoming matchups in MMA and boxing.

In MMA, Michał Michalski is scheduled to return to the cage on September 19 at XTB KSW 121 in Liberec to face Radosław Paczuski. Paczuski is returning to KSW following a year-long hiatus after a knockout loss to Piotr Kuberski. Additionally, Michał ‘Matrix’ Królik has addressed his upcoming fight against Marcin Sianos at FAME 32, describing the matchup as a ‘David versus Goliath’ scenario due to physical differences. Robert Bryczek is also set for a UFC return on September 26 at the META Apex in Las Vegas, where he will face Brazilian Rodolfo Vieira in a bout expected to pit Bryczek’s striking against Vieira’s Brazilian Jiu-Jitsu.

In boxing, Michał Cieślak is reportedly in talks for a WBC cruiserweight world title bout against David Benavidez, potentially scheduled for December 12, 2026. Meanwhile, a heavyweight clash is being prepared for the Rocky Boxing Night event in Koszalin, Poland, this October. The main event, which is reportedly ‘90 percent certain’, features Kacper Meyna and Damian Knyba competing for the International Polish Champion title. Both fighters currently hold 17-1 records and are ranked within the WBC top 25.
