It's a clash between European heavyweight kickboxing veterans! Polish Muay Thai & kickboxing champion Tomasz Sarara (1-1) and Dutch kickboxing legend Errol Zimmerman (0-1) will take place in the co-main event of XTB KSW 81 on April 22.

Sarara's two fights in KSW have been nothing short of incredible action-packed bouts while Zimmerman won his promotional debut with a TKO win over former KSW heavyweight champ Marcin Rozalski in a once-off special rules bout.

The duo will meet under MMA rules in a fight that promises to be fireworks!
