This Saturday, January 15, Marian 'Golden Boy' Ziolkowski (23-8-1) will defend his KSW lightweight title against former welterweight champion Borys 'The Tasmanian Devil' Mankowski (22-8-1) in the main event of KSW 66 live on PPV!

Ziolkowski won the vacant lightweight title at KSW 57 at the end of 2020 with a flawless win over Roman Szymanski and has since defended the title once by submitting KO artist Maciej Kazieczko this past April at KSW 60. He is now relishing the opportunity to defend his title against one of the biggest stars in KSW.

Fans have been wanting Mankowski to challenge for the title ever since he dropped down to lightweight last year. The 32-year-old defeated UFC veterans Jesse Taylor, David Zawada, & John Maguire, to just a few, during his reign as welterweight champion. However, after losing the title to Roberto Soldic he was forced to reassess his career and set his sights at becoming a multi-weight KSW champion.

KSW 66 will be available to watch live on Viaplay in Scandinavia, Poland, and the Baltics, and worldwide on www.KSWTV.com and the KSW App!
