KSW 121 brings nine fights to Home Credit Arena in Liberec, Czech Republic on Saturday, September 19, headlined by a heavyweight clash that only exists because the promotion needed a new opponent for Štefan Vojčák. No title is on the line, but a main card six fights deep and a full undercard of Polish and Czech regulars make this one of the bigger KSW cards outside its flagship numbered PPV events.
