If it’s one-punch knockout power that you want from a fight, look no further than defending KSW welterweight champion Roberto Soldic . Faced with an unbeaten foe in Krystian Kaszubowski (7-1), Soldic (16-3 MMA) needed a single left hook to crush his challenger’s title hopes in the first round of KSW 49’s final bout Saturday. And STILL KSW welterweight champion! The RoboCop Roberto @Soldic_MMA !!! #KSW49 pic.twitter.com/0cL2LWRBo8 — KSW (@KSW_MMA) May 18, 2019 KSW 49 took place at Ergo Arena in Gdansk, Poland, and streamed live on DAZN.
